Heatsink Installing Experts Apply within

[zombiebeat]

I am trying to install a Silentmaxx Coolflow 2800, my system boots for about 2 seconds then shuts down (I'm assuming this is my BIOS CPU Temp safety feature).

I've followed the AS3 application instructions carefully, when I take off the heatsink there is a small square indicating that there is contact between CPU/Arctic Silver/Heatsink.

What's even more puzzling is I pop back on my trusty old Coolermaster and everything is fine.


Edit manufacturers site
Any ideas or suggestion welcome.

Thanks, zombie.

how much does it weigh? and what fan do they use to make it quiet?

does that fan have a 3pin or 4pin power connector? Some motherboards have a safety feature where you have to have a RPM (3pin fan) connector plugged into the motherboard so it knows there is a fan on there to keep the CPU from overheating.

It could also be that the fan is just spinning too slow and your bios protects against that as well

Edit: it's 550g (good job I don't sell fruit ) and it's a papst fan

It's only has a 3-pin mobo connector

Maybe you put it on backwards?

It may sound dumb but it happens.

Also, I once put my heastink on in such a way that part of the base was resting on the top of the socket, so of course only almost no contact was being made except for the very bottom of the core

All I had to do was unmount it and slide the heatsink down a little, problem solved.

Benny I tried different orientations after your suggestion, no luck


I think your thoughts on the H/S resting on the socket may be correct though and I suspect this is a result of how the copper has been machined by the manufacturer.

If the heatsink is resting on the socket, it's because you put it on wrong.. lol

I did it once without realizing it. The way you can tell is when you take off the heatsink, look at the thermal paste and examine the imprint.

There's a little play in the heatsink bracket sometimes, not necessarily a design flaw, just the way it is sometimes. This happened to me on my thermalright SLK900A.

Just take it off and put it back on, making sure the heatsink isn't resting on the big part of the socket.

No I'm definitely putting it on correctly.

What I meant was the the small "step"(lip, whatever) on the base of the heatsink is not high enough to clear the edge of the socket

I checked the thermal paste I got with the heatsink and it's a generic brand, the last thing I'm gonna try before I RMA this is bona fide Arctic Silver and see if that makes any difference.

That is bad. So your heatsink is at a slight angle when attached? Your HS isn't making contact with the core if it is at an angle. Do not put your HS back on again because you could crack or chip the core if it is at an angle.
