My grandparents have this exact Dell except it’s rocking a Core2Duo, I swapped an SSD and a fresh copy of windows 10 4 years ago and even though it’s still working like a champ I always found weird how under normal usage the drive temperature would be 60 C most of the time. Great PC for really basic tasking though!

Used an SX280 (precursor to this) as a home server for a few years. caps started failing so I replaced it with a 760 USFF motherboard and had to kludge up a fan to make it shut up about the drive fan failing. I kept a 2.5" drive in the caddy and one in the optical bay with an adapter... it worked rather well. Had an E8200 in it most of its life but later dropped in the Xeon equivalent of the E8400 which had a lower TDP. DA-2s are hard to find these days in good shape as they also suffer cap plague issues and anyone that had them a few years ago sold out for lots of money selling them to GPU miner farms.

Drive was good but it didn't post with both 1GB stick in. I read this model can forget it's BIOS settings and after a cmos reset with a jumper, it accepted both sticks of RAM and worked perfectly. It's impressive to me they made a Core2 duo class computer so small. It would be a king hooked to a living room TV with a couple wireless Xbox 360 controllers playing retro games with a CRT GLshader. The CPU cooler looked like solid copper. Awesome.

Have you thought about trying to sqeeze a little fan on the left vent. I'm not sure if intake or exhaust would be better. But could maybe help keep the air that the hard drive recirculates cool by either expelling it. Or by bringing cooler air in for it to use. Maybe if you're real lucky it'll blow the old hot air to the right and towards the cpu fans and out the back. Maybe one could be put further into the case blowing towards the cpu cooler. Might help keep the ram cooler and move that hot air to the cpu fans but i dont know if getting one ot both of those to fit would be possible. A simple exhaust fan out the left might be better anyway to not give the cpu any mire heat to deal with. Love your videos, would be super neat to see you try and fix this ones thermal design like you did last time.

A redesigned air duct stealing some cool air into HDD area would help tremendously, since the CPU is already well cooled. I always get fascinated by these old SFF systems, good thing we have way more efficient hardware(and SSDs) that getaway with pretty bad thermal designs.
@aprilkolwey47798 ай бұрын
I have the SFF version of this thing here, which has an... amusing cooling setup - it's more or less the same story with air going in the front, through the CPU heatsink, and out the back.. except the hard drive is right behind that heatsink, so the hot air from the CPU heatsink just blows directly onto the hard drive. Thankfully mine has a Core 2 Duo in it.
@MichaelFlatman8 ай бұрын
I think, disconnect the front cooling fan, leave the rear one and hdd one in. The negative pressure from the rear fan will draw air over the heat sink, keeping cpu cool, but also draw some air in from the vent near the hard drive cage
