cooling problem i7 870? (first intel)

post #1 of 9
Thread Starter 
Ive seen some folks who've run into things like this. But haven't really found a fix. I originally had the 870 on a maximus III gene cooled off by an h50 (2 cm r4s in push/pull) and a bagillion case fans. Kept going to 99 c...reapplied TIM idled better but still 99 c under full load.
ok this could entirely be my fault because im using some diamond compound that's suuuper hard to apply instead of my default as5.
so I tried a new route, cleaned the cpu and stuck on the garbage stock cooler. Temps stayed warm.
noticed voltage (which was set to auto) was somewhere around 1.13 I guess that may be high for an intel so I dropped it a couple of times down to .99 volts

Temps got more manageable, but when I run prime slowly go right back up to dangerous.

By the way at 3.014ghz with ht on, no turbo.

Being my first intel (not really I've had two c2quads workstation and built a million intel workstations ) .99 volts seems low but maybe im way off base but im pretty sure 99c is a little too high lol

Thanks, and let the flaming begin

Are you sure it is 99c? i think your temperature software might be off or something as that is very high, use real temp?

Also i would try the h50 with as5 make sure its clamped right down as the only way you would be seeing these temps is if your cooler was hanging off lol or you chip is faulty.
The pump in the h50 could have gone, but because you a re using a stock cooler now and its still high its not as likely.

99C is way too high for an i7 870. You better get some real thermal paste and apply it.

You could literally bolt a stack of pennies to your chip and stay below 99C, something is wrong there. Do you have a massive kink in your tubing and are you sure the pump is connected? If it's still at 99C on stock cooling either the chip is faulty, the cooling is upside down or your temp software is wrong.

Edit: In case that comes across as me being a dick, I don't actually think it's upside down
Just there's no way it should be that bad so there is a huge problem somewhere.

Im hoping it's the temp software...I typically just use speed fan. PC wizard does no confirm 99c so when i get the chance I will probably try "real temp"

Yea I'm not sure what the deal is with my h50. I tried it on a core 2 quad a while back and never got it to cool effectively there either.

I always hook it up to the CPU fan header and crank that up to 100, or i've tried just connecting it to a molex, neither has really helped.

Im thinking of tearing it apart and figuring out what the deal is one of these days when I get the chance.

and no you did not come across as a dick or chocolate bunny or anything I might be offended by

To All:
Thanks for the brutally fast replies

Did you plug the H50s pump in?

How are you applying the TIM? A rice grain sized dollop in the middle seems to work best at avoiding air bubbles.

take a look at my sig rig .. 870 @ 4.4ghz / 1.45v and im using a h50 i never see above 80c .

Something major is wrong , definatly should not hit 99c at 3ghz / .99v

check to see if your pump is at 1400rpm , it needs to be working at full speed to flow the water efficently enough to cool it down in time by the time it gets back to the cpu .

go back to as5 , thats what im using and its great paste . and tighten ur block as tight as it can be , make sure you dont smudge the thermal paste while trying to twist the pump into the ring cos then ull have to start all over again , i thought it was going to be a never ending process but i finally got the perfect seating and i haven taken off my pump now for months ... goin great =)

hope u figure it out mate

p.s apply the thermal paste like so on an i7 870 , no other way of applying it got good results use the line method only .

agreed, but ive never had a problem with speed fan before, and i figured since its a fancy schmancy ROG board theyd have super good sensors or whatever

Yes to the CPU fan header (turned up to 100% in bios)

I've been using the ghetto fab spread it flat and thin method for a loong time successfully will try something new though

Thanks for all the wisdom I will take this to heart and try out the line method...(although apparently you are lapped so I've got to assume its a little bit different)

and 4.4?!? that's awesome man...btw what fans are you using on your h50?
