mugen 2 temperature problem (Asus P6T/i7 920)

[tangy ziz]

Hi everyone

so I recieved my new pc today, after having a friend of mine who is more experienced at assembling pc's put it together (i have the knowledge, but i've rarely had to put it to practice) set it up for me.

Now he'd mounted the fan on the top of the mugen 2, blowing air downwards. Right next to the 200m fan on my antec 900.
Which blows air upwards.

I know right, dumb?

So I swapped the fan around to be pushing air in from above the ram slots, so the exterior fan could then push the hot air outside,


After much fiddling and fickering to attach the fan clips without removing the mobo, i noticed that the mugen was wobbly.

With a small amount of pressure, I could make it move maybe half a centimetre either way.

Realising that this was going to seriously effect the performance of the cooler, I checked the idle and the stress results (having not done so previously since i'd only had the pc for an hour or so)

45 degrees idle, 100 degrees+ after a minute in prime95, on stock speed

So in conclusion, what can I do about this? I'm not so keen on removing the motherboard, although I could if i really had to,

My advice is to take off motherboard again and re-install hsf. After re-installing see what happens with temperatures and post results...

so it's going to come down to taking the mobo off reguardless?

I'd like to try just tightening it down first since I don't have any spare thermal compound if I was to totally reinstall it

edit: trip report -
after a pantshitting experience stripping the pc down till i could take the mobo off, i was only able to get maybe a quarter turn of the screw before it felt like i was applying undue force


washers appeared to be fitted although I couldn't be certain, since I wasn't able to quite clearly see it

anyway, after fitting the case back together, and turning my antec 900s case fans to high, my idle temps have gone down to 35-36c (and I now have an industrial wind tunnel on my desk)


HOWEVER

a minute of stress testing in prime95 brings the temps in realtemp up to high 80s/90s with RAPID speed

(this is within 15 seconds of starting the test)





So I assume this has something to do with the way the thermal compound has been applied? Should I just buy another tube, strip down the pc again (oh god aaaaa), clean off the old compund with a q-tip of methylated spirits & mount the thing myself, making sure a completly even application this time round?

hi,


your temps are damn to high, and more then 30-40°C over normal Temps. Du you be sure to peal of the film on the base? how much thermal compound you use? normally this little bag comes with Mugen 2 is enough for 5 cpus. A spot with the size on a pea is ok. Fan spinns and how fast?

that's the thing, I wasn't the one who installed this CPU/heatsink, ergo I can't say about the sticker/thermal grease

as the person who installed it is usually pretty adept with pc hardware, i can atleast assume he removed the sticker, but as far as the thermal grease goes, I have no idea


I haven't been able to contact him to see if he kept the thermal compound, fearing the worst i already have a tube of artic silver 5 in the post which should be here in 2 days or so

What he did say is that he had a bit of an issue fitting it (saying it took him a long time because of how unusual it was compared to his usual-fare of stock coolers)




Should have installed the damn thing myself, still incredibly squeamish about taking the pc apart/putting it back together again even if i've done it multiple times

e: fan's running at max speed i believe, all my antec 900s case fans are cranked up to high and it sounds like i have a windtunnel next to my monitor~

Hi,


its necessary to know if he doas als the things right. so maybe you should try to de-mount the cooler. its not that difficult. after this clean the cooler and the cpu, maybe make pics, and reinstall the cooler. that should help

I also have Mugen 2 On P6T (but deluxe v2 version)

The thing is that it seems that my temperature is also too high.

I'm using standard thermal interface. Temperature reaches 90 degrees.

When I removed intel backplate and installed Mugen's backplate I noticed that socket plate is loose and I couldn't put any more pressure to screw backplate.

Could this be the reason for high temperatures?

Hi,

the socket mounting of 1366 is not 100% fixed, that's normal. but there is no influence at the pressure or something else. We had many peoples with the same board and without problems. Maybe you guys should recheck your thermal compound imprint on the CPUs heatspreader and post it here.

I followed another suggestion i had seen a while back, by turning my pc case on its side

this dropped the max temperatures down to what could be considered 'normal' (still a little hot for stock speeds) and dropped idle temps down to 30 degrees

So what can I do if my cooler no longer provides proper cooling when my case is upright?

Well that means your cooler doesn't fit close enough to cpu. You may have to screw it closer to MB.
