What are good temps for 4 Sapphire 5830s in a MSI 890FXA GD70 (yes they are cramped together)?

I was getting up to 85c with the middle cards. Is that normal/good/bad to continue running 24/7?

All 4 are OC 1000/300.

I know that most people think that below 80 is a good idea but it seems that there temp threshold is around 100c so i should be ok.

any thoughts would be great.

Yea, 85c is fine, you could possibly add, that is if you are on a tech station, lay a few 120mm fans on them, fanning air in/on them. I think they could even hit 110c-120c but then they will prob be no good after that kind of 24/7 abuse in a month or less. See what others have to say. I've pulled my system out of my case laying out on a microwave stand to keep the GFX card cooler. Perfect fit, all components on the surface of the microwave stand.

Well i have them in a XIGMATEK Elysium case. i wanted them there to keep the noise level a bit lower.

I used to have AC blowing straight from a convector which kept them a cool 60c to 63c but the noise was just too much for the room. I dropped them into a XIGMATEK Elysium which has the massive 200mm fan on the side blowing right on them but that also pushed the temps a bit high. (past 90)
So I added the following:

2 120mm directly behind the cards blowing out across the cards
4 80mm resting on top of the 5830s

Now they are around 85 with the GPU fans at 100. I hope i can drop them to 70 with out the temp going to high.
Thanks,

Be careful, as if you have A/C blowing directly, you could build up condensation on the components. As looking up convector, I am guessing you had it blowing in to a cooling radiator.

Yes, the convector is part of the building HVAC system. Its a duel pipe system (one pipe in one pipe out) meaning that its either cold (summer ac) or hot (winter heat). It has cold water running through a radiator with a blower fan under that forcing the cold air up into the room. I directed this cold air to back side of the mobo and 5830s with those 2 120mm fans and added to 80mms fans on the front side near the dvi ports to exhaust the hot air. It worked well keeping 4 cramped 5830s at a cool 60c - 63c but... Yes, condensation was a concern. Another reason i wanted to get away from the AC solution. I really just need somebody else that has confirmed the 85c is ok to run at.

What kind of VRM temps will 85c produce?

It depends on so much, what kind of heatsink you have, heatsinks on the vrm's, memory clocks, core clocks, ambient temps, fans, tech station, closed case. Only you could answer your own question. Mine are on a change all the time as night becomes day, sun beating on the house. I'm always changing my core clocks when I'm at the pc to leaving the pc.

Re-apply thermal grease.  People have used arctic silver and have reported better temps after applying them.

there's even a post about this subject here on the forums with pics and instructions.  you'll have to search for it.

arctic silver 5 works very well it has drop my temps by 3 to 5 degrees, my rigs are normally running around 74degrees and on really hot days may peak to 82. here is my setup

AS 5? negative.

it needs to be thermal cycled over a week or so to break in and set for max performance.. IE turned off for several hours at least every day or so for a week.  like, you want to do that with your miners? it also tends to dry out and needs to be re applied every year or so, if that matters.

artic cooling MX2 (for example) dropped my ASUS directCU 6870 temps 7 C.. and thats not their best either. its just very easy to apply, no break in, apply and go 24/7.

check around, there are better thermal pastes than AS 5. ICD7 (diamond based, it rocks but is hard to apply), AC MX2, AC MX4, Tuniq TX2.. theres more these are just off the top of me head.
