fx-8120 + sabertooth 990fx - Page 2

post #11 of 57
Although a Thuban processor is made differently compared to a Bulldozer, when I switched from too much thermal paste to 1 bead in the middle, my temps dropped 4c average at idle and 2c with prime.

ok, 1, you are using a rather low end air cooler on a chip that is known to be very "hot headed". 2nd, you are applying the paste wrong. on the 212+ you need to apply thin lines of the TIM along the cracks of the 212+ HS. that is the best way to apply TIM on a 212+. on other, non direct pipe heatsinks, the single dot in the center of tim is the best way. but if you have ever applied a dot on the 212+ then removed it you will see where that is flawed. Do what i suggested and your temps will drop somewhat but not much.

I am also running two video cards at full load doing 2 BOINC GPU jobs and producing higher temps for the motherboard.

PCIE1 - 56c
PCIE2 - 52c

GPU1 - 79c
GPU2 - 82c

To support my OC, I used the DIGI+VRM to up my CPU Load Line Calibration to Ultra High and the CPU/NB Load Line Calibration to High

sorry ,miss read your post,thinking you put 1.7 volts,which is nuts.

Hes using the 212+ EVO Difference being that the evo has an even copper base (no cracks to fill). At least thats what Ive gathered from all the evo pictures out there. And I wouldn't consider that a low end cooler by any means. The only low thing about it, is the price!

500

Its been my experience that the shin-etsu paste has horrible spread-ability. I would take one of the members advice from an earlier post and manually spread it on thin.

im pretty much at idle now... temp straight from thermal radar.

379 379

653

papas - 2advanced is correct there are no gaps, its flat.

2advanced - as i stated before i tested how it was gonna spread before i started

mrpreforations - at 1.7v this thing would blow up as it is now, lol

Hawtoothpk - enabling those features counter acts the voltage drop thats happening but its also raising the temps even higher. in the asus turbov software voltage is at 1.21250. setting LLC to high raises the vcore to this.

just for comparison's sake... 438

i am liquid cooled. but i am starting to think you have a case wide air flow issue... all temps seem high.i got an antec spot fan for my vrm's which helped quite a bit. pic for example..700445

UPDATE:

upgraded to a Fractal Design Arc Midi. Only using the included 3x 140 fans right now but 5x cougar 140s are on the way. I have also remounted the cooler, yes the tim was lacking, not enough over the area. mx-2 now, plenty applied.


front
450

back
450

idle @ 4ghz
338

load @ 4ghz
339

ambient temp is about 76f

to me the temps are still too high exp with this case and tim at this voltage.... thoughts?

it is stable at this voltage though at 4ghz... have done all prime t tests over 1hr and 3dmark and pcmark without fail.


im obviously not water cooling but i didnt want a case without the option, i will be upgrading. question is, is the cpu defective or am i missing something? cause imo its still too hot!?!

its just dam hot matt.
i cant get above 4ghz due to heat.

i just tried to test mine at 3800 and hit 61 in 3 minutes and just proved how good my heat sink is ,in about 30 seconds the temp droped by 10c.
if yours is the same its not the paste or sink.

just testing out your lower voltage idea,and it seems to be working,thanks thumb.gif

i got my 3800 @ 1.25volts @ 58c and prime small fft for 1 hour,seems stable.

5x cougars fans in....

2 fractal in front pwm 12v
1 cougar in bottom 7v
1 cougar in side pwm 12v (this one and back are only two unfiltered, been hard finding a good 140mm filter, suggestions?)
2 cougar out top 7v
1 cougar out back pwm 7v


idle
337

load
338

ambient temps are the same. i am guessing this is normal now or i have a defective cpu....?



ps
for the record ide recommend these fans to anyone... exp at $12/each. ive never owned a noctua but idk how they could be that much better at this price.
