Under 120 C is technically safe. I keep mine under 100 C to make them last.

Tolerance is a sign of weakness.

Ok good, lets get some moar MHz :evilgrin:

EDIT: Hit a lockup at 960 and 1500, ill probably leave it at 950 and 1450 for now, thats damn good for a air cooled dual gpu card

I almost thought you were talking about GPU temps there for a second :lol: Looks strange seeing that as the 1st post on page 2 :wacko:

:lol: Yeah I can see how that'd be confusing.

My VRM temps on my 5970, even under water cooling, still break 100 C occasionally if I'm doing something particularly intensive (IE: a Furmark-esque benchmark). Other than that, in games, I don't think I've seen over 70-80 C. :cheers:

Nicely done muchoman. Bravo..

I would think now that the stock cooler had either a defective heatpipe or something causing that issue

"It works Because I threatened it. :lol:" - " did you show it the sledgehammer" - "No, A flight of stairs"
"I don't want to be much of a forum Nazi but this situation calls for a hail Bosco and blitzkrieg someone".

If that does not fix it I hop in a Timber Wolf and Blast it to microscopic Particles.

Well thanks for your help with this, im fairly sure i have hit either the memory or core wall at 950 and 1450, with stock voltages thats a nice overclock anyway.

After extended gaming that uses both GPUs the highest temp was 68 on the top one, so this cooler is doing a damn fine job

Thanks for the encouragement.

As for the stock cooler, its a vapour chamber design.
I have been trying to pull it apart for ages, but it has tiny tiny screws holding it together, and three of them do not want to go anywhere, the rest came out after a struggle

I would go for it, Arctic Cooling make a 5970 cooler thats triple fan.
This thing is silent, and im running an open air testbench, so it is truly silent


On a unrelated note, im trying to decide if its worth it to increase from stock voltages, cause i cant hit 960 core with it atm

I'll have to check on some reviews on the dimensions but it should fit, but I'll need to fab my HDD section a little more haha
(older pic of original fab, I two front USB hubs plugged in underneath now as well

Edit: Just priced it and it's just shy of $93 :mellow: ....I think I'll pass, I could just get a more efficient/equal-better performing single core card with the sale of my 5970 and the extra $93 I feel. Oh well, it did seem to perform wonders in the reviews I saw

Mythos are you ever going to retire that case?

Man these spammers are geniuses...put (NO SPAM) in the thread title to hide the spam.  It's brilliant.  Hopefully this doesn't catch on...what if rapists wear signs that say (NOT A RAPIST)?  They will be raping everybody! D:

Yeah, they certainly arent cheap. When i bought the 6990 the guy wanted to sell his Aquacomputer block with it, if i were keeping this card i would have got the block cause im watercooling, but this card is going to a friend who needs all air

Yeah, looks like that case has been through a lot. Loving the ghetto look of the bent back sheet metal though :lol:
