High temps with XP-120

[damstr]

Well i got my new DFI mobo and can finally use my XP-120 which i have been dying to use, but my last mobo had compadibility problems so i couldn't use it. anway i got it installed and load temps are around 55C with my FX-55 which is a stock clocks, which is is about 5C lower then the stock cooler WTF!

i positive that its making contact with the CPU and that i have that right amount of thermal paste on the CPU so thats not the problem. it could be a temp probe problem, or someone told that the IHS could be making poor contact with the CPU itself.

any ideas or suggestions?
-thanks

For better answers, start your threads in the proper sections... Proper section for this one would have been air cooling section.

sorry, i posted this in another forum and it was the overclocking and cooling section for some reason i thought it was the same here. sorry :doh:

What kind of Thermalpaste did you use? Maybe your IHS is lopsided? Might be your contact / IHS, that would be my best guess ..

Two things.

1. The base of the XP120 is always extremely concave, so you'll need to lap the poop out of it.

2. Your IHS may not be making perfect contact with your core, so you may want to remove it.

2. Part B - If you do remove the IHS, you'll need to sand down the six protruding points on the XP 120's plastic mounting bracket about 70-80% of the way to make good contact again.

have you tried reseating it a few times? what kind of thermal paste

For best contact, use a BB-sized dot of thermal paste in the middle of the IHS. Spreading a thin layer will yield horrible results if the heatsink and/or IHS are concave as there won't be enough paste to fill the gap and you'll have an air pocket.

Took me about 4 hours to get mine flat but is was worth the effort. I dont have an FX55 but my 3.0c was a hot chip and i could keep load temps around 45c with 1.65v. Also what type of fan are you using? I bought a cheap Dynex 120mm fan to replace the 120x38mm sunon i had on it and dropped 2c.

yes i've tried reseating it a couple of times, im using AS5, and im using a 120mm Panaflo. i'll try just putting something the size of a BB on the cpu then putting the heatsink on. before i was spreading it out.

i would remove the IHS but i don't wan't to screw anything up because this is an expensive chip.
-thanks for the replies, i'll try some more things and let you guys know how it turns out.

[cartmanea]

Yeah, I wouldn't remove the IHS on a chip that spendy. One think you should do is doublecheck your cpu voltage with a multimeter. Find out where to measure the mosfets on the board with a multimeter and see if it is regulating properly, it could be overvolting slightly.

What fan are you using with the XP-120? Also, how much time have you given the AS5 to cure each time?

[damstr]

well i won't worry about it too much now, because im getting an X@ 3800+ and running it all on water, i'll worry about it then i guess.

and im running a 120mm Panaflo thats rated @ 116CFM

Try SI-120, its better.
