W870cu cpu heatseak seem to not sit properly

after some test, and after i've removed the heatseek, it seems like all the thermal paste don't touch all the core (about 80% of it was touching it). My temps was around 51 idle on 4 core but grow very high with gaming. All my OC gave me a BSOD so that's why I gave it a look. I try to put some thermal back but it never site back to touch all the core, even with a ton of Thermal paste. I've try with a shime, but it don't help much. It's not that I want to OC, but the FAN are always blowing on this thing like crazy when gaming.

By the way, I apply artic silver 5 and have a i7-920X

Is there a mod I can try to make it sit suitably ?

Thanks

 

It is a common problem and partly why I went back to using a GTX 285M. See here for possible solutions and see here for potential issues due to the solution.

By the way, I see no reason to use AS5 when there are other good non conductive pastes around.

 

I have almost the same rig as you do, and I can honestly say the fans are not loud at all even when I have my cpu temps up around 85C. It actually worried me that i couldn't really hear the fans very much while at that temp, so maybe I'll have to take a look at it too.

 

You should never use "a ton of thermal paste".

There doesn't seem to be anyone else reporting your heat sink issue with the CPU so i'd suggest RMAing.

This was about the CPU though. I suppose the fixes could be applied here as well.

 

Well since it work fine and don't give any BSOD without OC I can't get a RMA.

To mount the heat sink I use the number beside each screw... maybe that's why it doesn't touch everywhere...

Edit: "ton of thermal paste" was only for test purpose

 

Hm, i see.
I'd suggest that since it BSOD when OCing it's not a stable overclock.
You probably already know that increasing it in small increments is the way to go. What are the original clock versus the overclock? Have you seen it being reported as stable by others?

My i7 620m idles at about ~45C between the two cores.
This is at stock clock and it's at about an 28C-35C ambient temperature.

If you believe your heatsink is not making proper contact that would warrant a RMA. Still, i haven't heard anything about the cpu heatsink not making proper contact and your BSOD is probably due to an unstable overclock.
