955 cooling issue, AS5

post #1 of 4
Thread Starter 
Two weeks ago I tried IBT for the first time and saw my 3.85ghz 1.45v overclock bump my chip up to 70c before I panicked and shut it down.

I decided to reapply thermal paste to see if it would help (I used too much last time). After reapplying the Zalman ZM-STG1 my temps in IBT dropped to 64c max. I lowered the overclock, of course, until my load temps were under 60c...usually hovering around 55-56c.

Last week I went out and bought some Arctic Silver 5 to once again re-set the hsf (I had used the end of the Zalman paste and figured I would try AS5 for a change). Temps dropped maybe 1c, which was cool.

The next day I made shrouds out of old 120mm fans and set them up on the push and pull sides of the heatsink and turned on my rig. It then reached 65c under IBT load before I manually stopped the test. I don't think it would've gone much higher, but it is still way too high for this chip. I then took off the shrouds to see if they had actually increased my temps. Temps remained largely the same, maybe even increased a little to 66-67c.

Anyway, I just dropped everything back to stock clocks to see what would happen and it reached 55c in IBT. That was....at....stock! Idle temps are hovering around 38c, which is the exact idle temps the chip ran on the 3.8 overclock.

Is it possible I applied the AS5 improperly or shifted the heatsink when applying/removing the shrouds?

Ambient temps are around 18c and IBT test was High. Thanks for the help!

It's possible you bumped it, but that shouldn't make too huge a difference. What kind of fans do you have on the shrouds? Without changing anything else, take the shrouds off and see what happens.

Wait you panicked at 70c?

OT:
You probably bumped it.

They are Enermax 80cfm 120mm fans.

I did take the shrouds off and the temps increased 1-2c....quoting myself "I then took off the shrouds to see if they had actually increased my temps. Temps remained largely the same, maybe even increased a little to 66-67c"

This chip is only rated to handle 62c according to AMD and most (myself included) like to keep it under 55c.



I think I shifted it after the AS5 was burnt in, but would that account for an overall increase of 10-12c?
