Did I apply too much or too little thermal paste? Maybe imporoper application?

post #1 of 27
Thread Starter 
So I have an extremely good i7 950- it's gotten all the way up to 4.8 ghz on less than 1.5 volts, but my temperatures at less than 1.35 volts are absolutely absurd. I'm hitting 84 degrees in prime95, and my cooler is a noctua nh-d14. I'm using the NT-H1 TIM. I just put a bit about 4mm in diameter on the center of the CPU, but there was a tiny trail off of it. I didn't really spread the paste around- I just sort of plopped the heatsink on top of it. Should I take it off and reapply the paste? Any tips on how to do it better?

4mm blob is good, as for the trail, it wouldnt bother the thermal transfer. So, I think youre fine.

as for the temps, the only way youre going to get better thermals if if you lap your cpu and void your warranty for 1-2C difference and then get watercooling.

Well, 85c is clearly not a real-world temperature. Also, strangely enough, my temps are no higher on linX than on prime.

Anyways, 1.344 volts is good for 4.30 ghz for me, which is pretty damn good

That is quite good but what fans are you using? you mentioned you were using the noctua nh-d14, but do you have a push pull setup or anything? if you don't that would lower temps and if you do try some better fans maybe

I'm using the stock noctua fans- I have been banned from spending any more money on my computer though (I'm 16, so college is the big issue right now) so I can't change out the fans.

put a strip along one side, and spread the paste with an old credit card type thing. a thin even layer.

not so much... applications go out at 17, and people expect big things from my school. A 4.0 weighted GPA doesn't even put you in the top 50% for class rank lmao

85 is too high for that cooler. Just high ambient temps or something? Not enough pressure?

The problem is the case. You need better airflow. Even the best heatsink is no better than the air that flows through it.

That can be a fine case, but not with stock fans. This is what I did with my NZXT Beta Evo, which is similar to your case:



Ignore that bottom fan. I had to cut a hole to put it in.

At the top, the front position has a 140mm intake fan and the rear position is covered. With the side fan in position and (this is important) with the back grill cut out and no fan there, I get better cooling with my case buttoned up than with the side door off.

OK, so you can't spend more money. You can remove every electronic thing from your case, cut out that rear grill with side cutters (I did it that way) and file down the cut ends. Vacuum the case and wipe any metal filings out of it. Then put it back together.

With the back open, your NH-D14 will be your case exhaust (look at item 2 in my sig). Now take the fan that used to be in the rear and put it in front. Test the temps. Take the side fan and put it on top as intake (close off the rear fan position). Test the temps. Try various combinations and test the temps.

The basic principal is not to achieve front-to-back, bottom-to-top case airflow, but to present the freshest, coolest air to your D14. A heatsink cannot cool warm air.
