Uneven heatsink

After all I bought 4 pipe heatsink for my aw17 p18e. But its uneven and I think its not reach the CPU at all when I screw it. What do you think about this? Is there any good thermal paste for uneven heatsink that have good viscosity? I want to over clock it, with grizzly conductuant when I apply it 3 drop I have better result but not good enough, with as5 it have teribbly high temp.

 

A friend said to me that , IC Diamond & Phobya nanogrease extreme are good choice. But I can have them with 1 month delay and I want to order the best one can I use. Plz help
.

 

IC Diamond is good for filling gaps, but cannot keep up with Condu when it comes to decreasing the temps of OCed CPUs.

 

What can I do?

 

First of all, you could sand paper your heatsink to get it more even at the contact area

 

You mean that , after sand paper I use conductuant again? Is not a better paste with more consistency for oc?

 

Condu is the best when it comes to handling these high OC-temps, nothing's better, imo. I have round about 15° less since I use Condu, went from around 85 with Kryounaut to around 70° with Condu.
But it needs good and even contact.

 

What a dreaming temp. For me its get hot as soon as 2 min. And after 90 degree I have vr thermal limit too.

 

Yes you have the Haswell generation, this one is known for generating more heat, unfortunately.

 

But , Mr.fox and others have 85 degree temp with 4.5 GHz core , I have 100 with 38 GHz!

 

That was the AW 18, if I recall correctly.

Did you check, improve your CPU fan also?

 

Yes buy turbo fan from China guy. Cicichen.

 

But if I adjust it for full speed , I have suddenly shutdown after 1 min!

 

I bought 4 pipe heatsink from him too, but the quality is not good unfortunately.

 

Yes, this same fan I have in my m17x, it's working super.

Your shutdowns seems to be due to CPU overheating.

I had also read about the quality of this heatsink being not soo good, then I didn't buy it.

First of all, try sanding and use Condu again (or use your stock heatsink with Condu).

 

Not overheating I think , because with autofan mode , I hadn't experience that.

 

Did you have any vram problem?

 

No, but I didn't push it too far yet, max. 4,2 GHz atm.

 

Hmm that's weird.

 

Everything are strange nowdays.

 

I had vr thermal limit even with 3.7 GHz , after changing fan and heatsink! I don't know that thermal pad helps or not.

 

On the VRMs next to the CPU there should be thermal pads, 0,5 or 1mm, don't recall exactly, think it's 0,5.
