A [thermal] compound(ed) problem

[XANADV]

Hello again. Here's the deal. I just swapped my Hyper 612 out for an H100i. I was doing 4.4 GHz on my 3770k just fine but never stress tested. After I swapped I ran Prime95 small FFT but ended up getting north of 90C. Then I dialed down to 4.2 then stock clocks; same thing. Next I tried reapplying thermal compound then ran stress test again; same result. I repeated that process a second time with no sign of improvement.

I may still be relatively new to this stuff but I know for a fact a 3770k can easily do 4.6 GHz on an H100i so something is definitely wrong with this picture. I am almost thoroughly convinced its my [crappy] thermal compound since my idle temps are crazy high like high 30s. Tried to spread the stuff when I reapplied the second time and I found that it was hard as a rock and just would not spread like it should.

So any recommendations on better thermal solutions guys? Or am I 'just doing it wrong?' BTW I am using Antec Formula 7 thermal compound (which I used with my Hyper 612 also) and my mobo is Maximus V Formula.

Happy 2013!

Get some Noctua NTH1 (i hope thats what its called).

Rock-hard TIM doesnt sound like its good..

90° for a H100 is way too much!

Agreed.

OK now its really starting to suck. I just tried several different thermal solutions and used every method of applying them to the heat spreader. I am still getting idle temps in the high 30s and full load temps at 80 plus even with no overclock. Something else is wrong and I am starting to think it might be the heat spreader in my CPU that is the cause of my problem. I have exhausted just about every trick in the book short of replacing my CPU and I am running out of options. What do you guys think?

Have you tried putting the Hyper 612 back on to see what temps you get! it could be the H100?

 

[Etlar]

What volts a you useing to get your OC to 4.4 ?..

I'll try that later if no other solution presents itself. I was thinking that might be a possibility too.

1.28V but now I am at stock clocks and voltage.

Then you have some problem, i do know my own cpu is a bad one. But i hit 60 on water whit 1.270 v @ 4.5 ghz.

Intel burn test to kick the ass out of my cpu more then Prime95 small FFT do..

I just looked at your build log; pretty impressive stuff. If I may ask, what is the highest performance you have been able to achieve with your CPU?

 

[Josh Weston]

1.28v is a lot for such clocks, tbh. Ivy is different to other architectures - you hit a point where the temperatures soar as you add more voltage. This point is usually around the 1.2 mark.
Get the volts down and your CPU will stop frying. It's not about the clock

Have not yet testet that, that i do know my CPU is a bad one. Need alot more volts then i will like to put in to it

I don't think it's the thermal compound. Did you use the one that came applied on the H100i's copper block? Did you clean your CPU after removing the Hyper 612? Also, the H100i has a software where you can change all sorts of fan speeds, do you have that installed? Is the H100i new?

Hmm. I thought it was higher than that. Oh well, point taken. We shall see what happens.

Also when OC, reach an unstable overclock with stock voltage, and then start increasing the stability, to make sure you got the minimum stable voltage needed for that clock. that way you'll keep it as cool as possible.

I did use the pre-applied stuff at first.
I cleaned with isopropyl alcohol every time.
Yes I bought my unit new and yes I use CorsairLINK.


@Josh Weston
I just tried raising clock speed while leaving voltage at 1.2V. A little better but doesn't explain why my idle temp is so high.

 

[dragoonk]

I'm having a tough time beliving that the voltage is the culprit here. It might be your H100i... faulty ( hate to say that ). but first you need to figure out if you're using it properly ( If it's mounted properly, if the fans are at max, if the pump is running at max ).

 

[Josh Weston]

Well, your idle doesn't seem that high to me. My idle temps are similar, if not higher. Never bothered me, to be honest. My rig's Folding 24/7 though, so it's never really idle.
I'm guessing you have EIST turned off? If so, this means that your chip doesn't downclock itself when idle. It leads to greater overclocking stability, but inevitably higher idle temps.

I take part of my last statement back. I use CorsairLINK to monitor my pump speed only, which is running at 2100 RPM if I remember correctly. And I'm not using the fans that came with it; Noctua NF-F12s in pull configuration @ 1200 RPM. Still I should get better performance than my 612.

 

[dragoonk]

Idle temps do seem fine, but the higher temps are more relevant here. We know Ivy's have a somewhat heat transfer "issue", but I don't think you've hit that limits with those volts. i'm running mine at a crazy 1.56V on a Phenom stock cooler and stress tested my CPU would reach 60C max in a warm summer day, won't even hit 50C in BF3 which is a CPU demanding game.
