Dell precision T3500: CPU heat nightmare

Rodney_21 · Oct 17, 2016

I recently bought a refurbished Dell Precision T3500 Xeon W5365 3.2ghz . It came from New Egg refurbished by "Tek Boost"

During benchmarking the cpu temps hover around 95C and can go as far as it to tell me it reached 100c for a second. This sucks.

I've had it apart, and it has a passive cpu cooler. Meaning just a heat-sink with some pretty hefty fans an inch or so in front of it. I'm surprised this thing cools at all.

I wish to add an additional fan mounted very close to the CPU , possibly building a shroud. I don't know yet.

There seems to only be one CPU fan plug on the motherboard. Should I tap into that or just take the power I need to run this any any more additional fans from free or unused plugs from the CPU? I would like to be able to monitor RPM and have it respond to speed demands like the stock cooling fans in the front but .. I don't know if you can or should splice into any wire for a PC that didn't "come with" a dedicated CPU cooling fan.

I probably will end up buying a better CPU cooler but I need anyone with knowledge about this system as it relates to cooling a passive CPU heat sink or anything else to please chime in here.

Any cooler recommendations are appreciated.

You could just measure the top of the heatsink. Get a fan with 4 screws and bolt it right on top. Use between the fins to wedge the screws tight. This is the old days way of attaching fans to heatsink.

You can buy a better CPU cooler, one with copper heatpipes for that system, and i just used fishing line to attach a fan directly to it

I ended up doing just that . Model U016f. The fan tied to the rear of it helps a lot. I plan to get a variable rpm fan because it still can get up there.

Speedfan also works with Dells I found out, I've learned a lot since I started all this. You just have to click the "use Dell laptop" option and it will read and increase RPM on the two front fans.
