Alphacool NexXxos XT 45 FULL COPPER Radiator Unboxing & First Look Linus Tech Tipsa

[@avispa987]

the two inlets in the top and the bottom is because there is an alphacool logo on the sides, and its orientation depends on how you use the rad, with the multiple inlets you could avoid that issue

[@meshary007]

Material strength is one of the biggest differences between copper and aluminum. Copper tubes that carry coolant have to be thin to keep a copper radiator cooling efficiently. Copper is somewhat weak, and tubes need to be narrow to prevent internal pressure from swelling. Aluminum is stronger, which makes it easier to use wider tubes. Using wider tubes allows for more direct contact between fins and the tube, which increases the radiator's capacity to dissipate heat.

[@w0ffe]

Linus Linus Linus; Brass isn't appreciably heavier or lighter than copper. We're talking 8.53 g/ml for Admiralty brass vs. 8.96 g/ml for pure copper; this is nothing like Aluminium at less than 3 g/ml.

[@TazarZero]

You almost got me with your profile image!

[@bujin5455]

1:15 Aluminum doesn't "dissipate heat better". You cannot "dissipate" any faster than you can conduct, as dissipation is a function of conductivity, and copper's thermal conductivity is nearly double that of aluminum, which is why in all cases copper heatsinks have superior cooling properties for a given design over their aluminum counterparts. Aluminum is lighter than copper, and much less expensive than copper, and for those two reasons aluminum is generally selected for over copper; if cooling is the ONLY design concern, than copper is the best choice, period.

[@kuhrd]

It also has a lot to do with having only one type of metal in the loop which should eliminate problems with galvanic reactions that take place in many loops using differing types of metals in contact with the water. Copper is a better conductor of heat than aluminum and so it offers a lower temperature delta between the area the heat enters from the water and the area it leaves to the air so it should offer slightly faster thermal energy transfer if the surface area of the rad fins are equal.

[@meshary007]

Copper was the original choice material in the manufacturing of radiators because of its superior heat conductivity. The biggest differences between aluminum and copper radiators are strength, weight, heat conductivity and appearance.

[@dhkenny2001]

ive used the same 360 and 240 rad from them for over 6 builds now and they are still going strong for the money u cant beat them i wont use any other brand rad thats how good they are

[@enessou]

Quick note: The screws are copper plated and not solid copper (I've cut one apart to shorten it and it's normal steel underneath). A solid copper screw would probably be useless sooner rather than later because of copper's softness. One would have to be very careful not to over-tighten it.

[@LinusTechTips]

Most new radiators have fins instead of tubes under the screw holes anyway, so it's a non-factor for me.

[@demaciu88]

Linus works for NCIX, which is a large retail store in CA, that's how he got started. He's also a professional unboxer, wouldn't you send him stuff to show people if you wanted tech savvy people to see them?

[@Rollergold4]

How did you forget the best feature Linus?!?! The protective ledge under the screw holes which greatly reduces the chance of screw damage.

[@PIayNice]

I have the very same in a Level 10 GT, dual up top and single on bottom along with strategically drilled holes in the case top and bottom for drain and fill ports...just unscrew a plug and done!

[@leihejun844]

2:28 Really, that would be great. Now thicker rads have two pros: 1- don't need static pressure fan 2- 2:28 If what you said here is true, I prefer 280 thick to 360

[@ColtaineCrows]

IDK much about watercooling, but the usual hydraulic system has several smaller lines out and then they all dump into one return, which doesn't necessarily need to be as huge as one might think. I've seen four 30mm feeds come back in a single 42 mm tube. But yeah, the way Linus explained it seemed a bit backwards to me aswell.

[@patpan8675]

Thermal conductivity (amt of heat transferred) of Aluminum is ~ 237, while Copper has ~ 410.

[@gutserker]

i'm referring to how long till the threading on the screws last before stripping. that could be an issue for people that rebuild their systems often

[@Hellbeast58-Official]

got the dual 120 rad already about lets say 2 months ago, its nice, heavy and great cooling with Pressure fans

[@KoolanceGamer680]

Those look a lot like the Koolance radiators. I prefer the "blockier" style radiators such as the XSPC AX series. I do like the additional holes on the side though; that could come in handy. I want a radiator with holes on both ends. They could do it if they added an additional pass through chamber. That would be sweet!

[@Mx2J]

yeah i understand that metals can get into the loop and stuff, and yes i know copper is a way better conductor, but it seems as if aluminum is lighter having quicker heat transfer idk. im not super familiar with this kind of stuff, thank you for the info.

[@LinusTechTips]

Very good point. With the metals in direct contact with each other, the corrosion risk increases dramatically.

[@gulperiundmuratsavuran8998]

This video is 9 years old, wow

[@SuperRantboy]

I think their point is he is no longer the (global?)product manager, which he was previously, at NCIX so he has no control over their inventory in terms of what they get and when they get it. Now he is more or less an "on air" personality for them on (I assume) contract with Linus Media Group.

[@gutserker]

One thing nice about a copper radiator is you would have all copper in the system. Copper and aluminum exposed in water cause oxidization, this completely eliminates that. As for copper screws...why? I wouldn't want weak copper screws vs stainless steel

[@turkey10000]

I would love to see the Alphacool Monsta triple 120 radiator review.

[@pjtruslow]

Dissipation is based on surface area and surface to air delta temperature. The faster the surface is warmed by more conductivity, the higher the delta and therefore more dissipation. The claim that aluminium is a better dissipater is just a bad excuse to use cheaper metals. Conductivity, as always, is king when surface area is unchanged.

[@Benjay1975]

Linus - Im very curious as to where you get these parts to review.. are you asking the manufacturers for them or are you paying for them with your own coin? very curious as to the reason's why you are making these video's as well? are you trying to make money from youtubes? whats the go? please explain the context behind your approach and actions.

[@FallingForgiveness]

HockeyMiles30 Yes, just make sure you get the same size fittings. They are both G 1/4 threaded.

[@pappo666]

these rads are awesome i have the quad 140mm in my pc and the cooling is outstanding!

[@RKTGX95]

Hey Linus, does this unboxing imply on to something ? (btw, it would mean the world to me and others if you'd do a video fitting this and other rads in the C70. especially the 240 one in the bottom and trying a 360 at the top)

[@FeuerToifel]

alphacool is now owned by aquatuning. so the v2 of the phobya radiators are basicly the same as the alphacool full copper ones.

[@TEDdeMedici]

These are the radiators you used in the bitfenix prodigy build?

[@MinecraftingPlatypus]

Hows does a water cooling radiator work? Does the liquid actually travel through the fins?

[@Turskaify]

If I were to use 2 of the 240mm radiators in "Sli" on the top of my case, with a total of 6 fans in push-pull-push-pull, exactly how much would it weight with liquids and all? That might be a big strain for a weaker case.

[@Mx2J]

is there even that big of a difference for copper and alluminum rads? say same thickness, would you get better performance out of a allum or copper?

[@MohammedBabur]

thats the coolest looking radiator ive ever seen

[@Leonard_Lewis]

Ok Linus, fess up was it Rocket or Rumble who made the hole in your shirt and will we see the hole making on LinusCatTips?

[@i4ROFL]

It seems cool in theory, but is the lower temperature worth the extra weight, and mostly, the extra cost? Well, I guess the weight factor doesn't really apply to a desktop PC, but still.

[@ukki87]

Can you do a custom liquid cooling with 2 pumps on 1 radiator? split up the loops so you got 2 loops running at the same raditaor

[@meshary007]

There are several benefits to both aluminum and copper. It is scientifically proven that copper transfers heat better than aluminum transfers heat. Copper is also easier to repair than aluminum in most situations. Aluminum, however, is generally 30 to 40 percent lighter than copper.

[@Tangylives]

I hope those screws aren't actually pure copper but a tougher alloy or copper plated steel.

[@Gunbardo]

Hmm... What about the black ice GTX radiators? Heard they were good...

[@Rollergold4]

Fair enough, I'm personally in the better safe then sorry camp though. Thankfully the XT45 is also a great performer in my loop.

[@Rollergold4]

I don't think NCIX carries Alphacool Rads. I had to get mine from FrozenCPU.

[@LevisL95]

Well the plugs and the screws are only copper coated, so maybe that isn't 100% copper or it has some kind of protective layer... Anyway Linus said on Alphacool GPU block video that usually copper is fine until you touch it with greasy hands. Then it starts to go green. So I guess it has some kind of protection that doesn't like grease. He wears gloves in that video.

[@Bupalooga1]

He is still working at NCIX, have to not seen the latest NCIX weekly? He just works there less

[@Crow2099]

Well. Just got in a Alphacool NexXxoS UT60 Full Copper Quad 120mm Radiator and the plugs are not copper and neither is the mounting screws. The LOGO is not in the center but now smaller and in the bottom corner opposite of the inlet and outlet ports in blue print instead of the big LOGO we see on it in this video and other pics we see on the online stores to buy it.

[@Nocure92]

Crow2099 Yeah.. I got the same. Bummer :/

[@laundryman200]

I run 2 xof thair 360 and 1-240 in my cosmos II ,,I just love thair products

[@HitMarkersAreFun]

very stylish radiators

[@kylefutet]

isnt this the rad for the bitfenix watercooled project

[@DavidGreen1993]

You couldn't have 3 going in then 1 going out, you would end up with a bottleneck there and different flow speeds of the fluid through the loop, unless your out tubing ID was 3x the size of your 3 in tubes ID

[@brechan69]

While it's all fine and dandy to showcase these (new to ncix.com) water cooling products, when will they actually be available for purchase from the store? I watched an overview video a few weeks ago - Phobya UV LED lighting strips - but to this day, I've yet been able to find them on the ncix.com website...not even listed as a brand that ncix.com carries. What gives?

[@rodrigomaero]

of course the G1/4" plugs are copper, if not there would be galvanic corrosion throughout the water circuit. that won't happen if every piece of metal the water touchs is the same material

[@XIII1987]

linus wheres the live stream link?

[@vettexl]

Is your pic Dwayne Dibley?

[@BELPHEGORLIVE]

Linus, check the Monsta radiators, those are thick :D

[@Dramaican88]

Can you do a techquickie parallel vs serial watercooling?

[@ronzombe]

i thought you said all radiators are the same linus im doubting my ek rad now

[@sokrutu]

@ukki87 possible, but stupid unless its a 9x120 or even larger rad

[@donut3110]

You don't want heat inside your pc. All of these people making a radiator as an intake don't realise that they're going to burn up anything that isn't getting enough airflow. The best solution is to have an externally mounted radiator.

[@Fusay34]

Can haf 912 plua fit that single 120 without modding?

[@theanimal735]

7950 msi twin frozr vs gigabyte 7950 windforce? the windofre is 60 dollars cheaper so which one should i get?

[@skifree0]

lol i was thinking the same thing. it would suck when your screwing in the block and the screw bends

[@hotshot619]

Gigabyte, I have a Windforce 7970 and I love it, can't say enough about Gigabyte or their cooler design. It's cheaper, looks cooler (imho) and it preforms great. Also a quick search on overclock(dot)net gave Gigabyte the nod and they know their stuff.

[@TheRattleSnake3145]

Did he mean series not serial?

[@xZoMbIeSx27]

What's the best thinnest Radiator

[@enjoiskaterguy]

NOTE TO POTENTIAL BUYERS: Be careful when screwing screws through the fans+radiator when time comes. I punctured 2 radiators due to no labeling by the company when they package the 2 different size radiator screws (which are for different width fans). There are protective metal plates underneath the screw holes that are meant to protect the screws from going too far but even with minimal screw in pressure, these screws will open up the radiator.

[@Alph92]

+LibertyMan not meaning to insult you but why did you just take the screws and screw them in? i mean don't you take a look and them and sevondly and most importantly why didn't you stop screwing the screw when you noticed that it got significantly harder to screw it in??

[@kadenwatt2033]

ironically, alphacool puts a VERY strong plate all around the perimeter of their rads to PREVENT that from happening. If you really went through that AND punctured your rad 2 times, then you miiight want to rethink your methods of watercooling...

[@enjoiskaterguy]

+Kaden Watt..... if by "very strong" you mean extremely weak aluminum then, yes.

[@enjoiskaterguy]

+OtterStrikesBack ....it wasn't getting hard to screw in. it just kept going. thebplates it has to catch the screw give little indication of its fastened-ness. my biggest beef I had was of its lack of labeling of the screw for specific width rad fans. its irresponsible product quality control which causes cases like mine to occur.

[@Bulwark1911]

Can't buy these at NCIX, please fix this !

[@Jedibenuk]

Posting from 2020. Oh how naive we were.

[@TheJupiteL]

welcome to LinusTechTips then :)

[@icesentry]

What's up with the lighting?

[@Nicktrance1]

COOOOL! get it?

[@HockeyMiles30]

Will the alphacool NexXxos XT 60 280mm rad work with the koolance 380i cpu block?

[@riejuroks1]

do you mean, UT60? Either way if you ask such a question you should not be attempting to water cool a system just yet

[@HockeyMiles30]

Oh thanks for the answer, but I've actually already watercooled my PC xD

[@enjoiskaterguy]

***** agreed!

[@triniraper]

i have question -- can u use that alphacool radiator on an all in one CPU liquid cooler ????

[@MrKZdemos]

No

[@vespaman101]

you can buy the eisbauer cpu block separate and make ur own aio.

[@eugenkrause5556]

How do you get those blue things out?

[@Dseated]

wont the exposed copper go all green?

[@TheGibberishGamer]

you have great vids but do something with the sound

[@azentioced9]

where can i buy some?

[@PointlessGuardians]

Good stuff

[@amasev]

that lighting

[@Breadfan00]

wouldn't that slim screw heads go through the fans?

[@enjoiskaterguy]

no they don't. unless you have a fan by some unknown fan manufacturer that doesn't use standardized screw holes.

[@Breadfan00]

LibertyMan Thx ;)

[@enjoiskaterguy]

sure thing!

[@kajalgo1524]

SLI Radiators...oooh yeah!!

[@welpelp4727]

Nice! LinusTechTipsa

[@bitmaxim]

Cool product

[@meshary007]

can someone tell me which is better Aluminum or full copper Radiator ?

[@CraftieGamer]

Why is there an axe in the wall?

[@patawic]

you should do that with any radiator

[@MeatyChunks]

I thought you were holding it with pink rubber kitchen gloves from the thumbnail.

[@jdp360]

SLI Radiators.... NICE!

[@AryanEimermacher]

Because why not?

[@andymawbzee]

like this one ? Coolgate-CG-240mm-CU-Dual-Radiator--Copper-Plated search for it with google It is sold by special tech in the UK

[@Imprudentman]

alphacool , not alcohol . Each can use ..

[@djaysenpai]

i also call it OCcool actually

[@jbads1989]

i saw alphacool in the video title and was like this is going to be crap. All copper radiator eh...not crap!

[@37061044]

Screw it, I'm buying this radiator and selling the extra copper parts for scarp. Saving money on my loop!

[@isaac9517]

nexectos?

[@NorwayVFX]

Linus, the title says Tech Tipsa

[@ryandonian]

Copper oxidizes, copper doesn't rust. That's why the Statue of Liberty is green.

[@Abenlog]

Linus actually doesn't work at NCIX anymore, so he has no input on when the products he's reviewing will come out on the NCIX website.

[@reiyu013]

does his shirt have a hole in his neck?

[@embersdestiny]

Coolgate copper edition!!!!
