Amd Heatsink (standoffs?)

[KraZy]

OK... this is a new one for me..

 

I was worried about my core temp at around 55c, and was trying to find the problem.. SO, I took off the heat sink, cleaned it, tripple checked the seating, reapplied the AC3... but still no go.

 

Finally, I took off those little foam standoffs on my chip, and -boom-. down to 43c.

 

Has anyone else had problems seating their heatsink with those things?

if you're talking about a shim then yes, shims arent good. If you're talking about the 4 little round pads on your cpu then no. And you shouldnt remove those becasue they keep your hsf from crushing the core on your cpu....and it keeps the hsf even on the cpu.

The shim I use still... if figure the more surface area of the cpu that has contact with the hsf, the better. And yes, I was talking about the 4 little pads on the chip itself.

 

Where is the trade off? I might be risking crushing damage to my cpu, but if the hsf is properly seated, and those pads were the problem, I say why not.

A shim should really only be used to protect the CPU from a misaligned heatsink, usually during installation -- and thus there should be a slight clearance between shim, H/S and CPU after installation. A shim should definitely NOT be the contact path between H/S and CPU. Heat must be taken off the CPU through the CPU die (glassy square area.)

 

A put a shim on mine to make sure I didn't screw up my CPU (self-trust issue ). Is was kind of concerned hooking up a big AX-7 with the 3 clip spring. In the end all went well.

 

Krazy, it seems odd that removing the foam pads resulted in such a temp reduction. This would indicate that they were somehow keeping the H/S higher than spec (i.e. not fully coming to rest on the CPU die...). Hmmm...
