First off, great product the HF150! Shielded most of the fat wires that traverse the radiator. Found noise on ignition/tach wire. I put a 1000 uF 100V cap across the two lugs on an HF150, but it overheats on , engine-off cool down for some reason. Not sure why.

Some of this resembles Nha Trang in 1969 when I was there. Nice music. And night shots tracers.

Hi Darryl Are you still making the No buss 50? Cheers

I've been a major fan of Mr. Darryl and his Autocoolguy controllers since i discovered him. I'm about to buy my second unit, this one for a new project. My first one is still on my 95 Mustang featured in his website and it's still working flawlessly since 2014!💪🏆

Have this in my 1947 Cadillac since 8 years ago and it works great

I have an HF125. Does the AC circuit "soft start" or does it jump up to the set RPM?

G'day mate. How much would one cost with freight to Australia? Regards Blair

Do you mean Spal Fan 411?

I just got 2 ,12 in spal fans , they have just 2 wires , hope that's good with an auto cool box, like a hf 125.

can i connect the sensor directly area where you connect the original temp sensor or should i get the adapter

I’ve been running the Auto Cool 85A on my Supra controlling two ford fans since 2014. Never had any issues whatsoever! Such a great product! Thank you!

Is this the controller recommended for a mustang gt with 2 brushed fans?

At the end u say its for diesel engines. Will this work for a mustang gt?

I have one installed in my 67 Mustang Fastback, and it keeps the engine cool during 115° days.

I bought one of these 2019, attached to two maradyne fans 225w each, the controller is amazing working like a champ, it is very durable with excellent build quality like a tank. Thanks Darryl🌹🌹

Seems like a great adapter! i’ll be picking one up for my dual fan set up i’m working on.

I'm very interested in the DX-150. Will this work on stock silverado dual fans? Or should I go with derale fans or flexalite fans?

Mr Darryl, I have a silverado 1500 putting a TYC brand dual contuer fans (stock style) pulling about 27 amps each on high. Will the 85 amp controller work with this configuration? Thankyou

Darryl I still can not find your email, phone number or any contact info. I need to buy your 125a PWM for my high torque Spal 16" fan

Why "From 50 amps..."? Can we control a 17Amp fan?

How much is this unit? (I gotta have it, just not sure when to call you at the shop) I didn't see it on your website being listed for sale or a way to purchase it.. Greetings from Tampa! And TY for your service!

can this control two lincoln mark viii fans? they have a combined max amp draw of about 80-82 amps at max speed. this would be a great set up.

Darryl knows his stuff. I purchased two of these units for two different trucks.They have been performing flawlessly for over 2 years now. Not one problem! The junk I had before was a joke. This is heavy duty, made in the U.S.A. quality here. Thanks Darryl! I'm going to buy another one soon for a Daytona clone I'm building now. www.ramchargercentral.com/threads/my-daytona-clone-project.326770/

I am using the blue 200 amp on my 1947 Cadillac to control 4 Spal 9" fans, unit has been working perfectly for the last 4 years and fans are even more quiet than the older spal PWM setup where I needed 4 pwm units due to the low amperage rating.

Can I correctly infer from you repeating the preferred location being on the outflow of the radiator that using the factory coolant temp sensor in the block’s water jacket is a bad idea? I just want to add pwm control to my electric fans and do away with the relays it currently uses

Is the Auto Cool III appropriate for a single speed MK 8 fan?

If I want to wire in a dash mounted 'fan off' switch (for off road water crossings) what is the best way to do this?

Can assume that the threaded sensors would need to be installed near the outflow hose (return to engine) as well? (Weld a bung just above the just in the tank)

Can you make it run for more than a minute after shut down say two to three minutes ?

I always come through the back and say hi to everyone in kitchen.

Jennys is my go to....where else can you come through the kitchen and ssy good morning to the cooks before you sit down.

Don’t waste your money on the No Buzz versions. My NB-50 doesn’t stop my Spal fan from buzzing. Just get the regular version and live with the buzz. The unit works great though.

I have the NB-50 controller. It works very well.....except it buzzes like a mf. Don’t waste your money on the No Buzz version. Just get the 50 Amp controller.

Hi Darryl this is Junior! Here’s one of tubing beader I found at Jegs P/N: 555-80083

Thank you for sharing your experiences, God bless you

Exceptional customer service, and Beutifily made products. American made, by a American

This turned into the 661st ordnance company in 1969 when I got there

Hands down the best fan controller I've found. Trumps Mishimoto, Derale, etc.

So cool that the only thing you showed during a VIDEO is basically a picture with sound. Wtf marketing company are you using? We Put You Out Of Business Soon? They must be based in China

What a great set of products you are designing. I have a question. I have my A/C condenser mounted in a remote location with its own electric fan. Which product would I need to control my electric radiator fan via PWM and the condenser fan separately via PWM in relation to pressure? From what I can gather from you website is to use the A/C pressure controller to operate a PWM fan controller. However, it appears that the A/C pressure controller only trips when it reaches the set pressure and wouldn't raise fan rpms in relation to A/C pressure.

Is this controller waterproof???

Hi Darryl, i just ordered this unit as well to monitor my Engine/Transmission coolers/fans. Do in need to hook up 2 sensors in series or paralell? So that wichever grounds first activates the Fan Controller. I bought the Setrab 180F sensors because they don't restrict oilflow. Tx, Harry

Enjoyed the video I was in Chu Lai ammo dump by the main gate July 69 - July 70 I was one of the crane operators loved my job

I was transferred from the 40th Ord. in Da Nang to the 295th in June of 69. From there to LZ Baldy an then back to Chu Lai when it became the 661st Ord. Came home 1/17/70

Just ordered one of these bad dudes for my Windstar fans going in my 69 Chevelle SS396. We will see how it works. Love to support a American based company with a man who answers the phone personally. Thanks sir and I look forward to installing your product.

Im building a turbo LS mustang with a rear mount radiator setup. Im running a 31x19x3" radaitor with a Lincoln mark viii fan. So my question is would this controller work on my setup?
