Xeon X5560 Cooling Help Needed...

Howdy, all. TIA.

I've been told that since the computer is a Dell Precision T3500, and there by proprietary in a lot of ways, there's really no way to replace the HS. HS gets air from two fans in front cage. I've added one 90 mm fan as exhaust.

Still, CPU temps seem high. Prime95 didn't kill, I killed Prime95 at the 90 C mark. Too high for an X5560, according to ARK.

Other than cable management, which I need to address, the only thing I can do is remove the HS, clean everything up, and apply fresh TIM. I bought some noctua NT-H1.

As I stated earlier, I guess there's no way to install a better HSF, so I'm stuck with this HS. It's pretty beefy, I'm guessing that the TIM that Dell used is just useless. Date Of Manufacture is 2009.

I really love this computer, and I can't afford to replace it.

I've searched YT for vids about how to remove the HS, add TIM, then replace it.


Do I have to pull the MoBo? Pain in the ass, it seems, not sure. Since I got the computer I've replaced the PSU, storage, and GPU. I'm not afraid to get into the guts.

[H], Need your input/help.

Definitely sounds like it needs to be repaired / replaced.

You could start with just replacing the fan, and reapplying some fresh TIM.

What size fan is it?

While you're in there, you could take some pics and measure the mounting holes and backplate, so you know what you'd need to be searching for in a replacement scenario. Could also measure the total height of the heatsink too.

EDIT: Re-reading your original post... is this the type of setup where the CPU heatsink lives inside of a plastic channel that's supposed to direct airflow from the front, with no actual fan on the heatsink itself? If so, those can sometimes be attached in a PITA type of way where it gets unscrewed from the bottom of the motherboard. (maybe)

So yes, you may need to disconnect and unscrew everything to lift it out and get to the bottom. Probably a good idea anyway if you plan to unscrew the heatsink from the mounting holes, incase the backplate pops off.

Actually, does it look like this?

That appears to be a fairly simple deal, but I don't know if the backplate will stay secured when you unscrew the heatsink? Would need to see the back of it, unfortunately.

There appears to be room right on the heatsink for a fan, so I'm not sure why they're not including one by default?

Apparenly a "heatsink assembly" module exists for this module that adds a plastic shroud, presumably with a spot to add a fan.

Or, you could try a little homebrew deal with a 120mm fan and some custom mounting solution and some elbow grease.

Your original issue is probably that the TIM is dried up - this will need to replaced no matter what you do about the fan situation.

It looks like this is the underside of that fan assembly/heatsink.

If your heatsink has these 4 small philips head mounting points on the bottom... you can probably use that 1TD00 fan assembly.

Looks exactly like that. The part that you are talking about is for T3560 and above. I have a T3550.

This is why I hate anything proprietary. But a good friend donated the computer to me.

All I can do is replace the the TIM. I'm very nervous about the process. I know it has to happen soon. My AC can't keep up.

Hey, usually, Piece of Cake, no problem, I agree. That's how it's gone for me with 95% of computers that I've worked on/built in the past. Usually the reapplication of TIM does a well enough job.

This is an oddball Dell server. I can't figure this case out. That's sad.

Well, the model number difference is so slight and they appear to be in the same family, so it may be the same shroud. If you look on the bottom of your heatsink while you're in there for those 4 screw placements it may be compatible. Can't seem to find any cheap ones though... but yeah a heatsink with no fan is kinda weak.
