Can do but atm its low on the list of priorities as im reinstalling windows 8.1 and bf4 currently.
How are you guys getting such low temps? What fan speed was that using Andy? Were you using vsync or an fps limiter? Got a pic of your case/fan setup? Got any side exhaust or intake fans?
Wrong priorities man!!!!
Well he is at stock!
In my 540 with 3 intake 120p's and 3 exhaust 120p's I saw temps top out at 86 degrees on GPU1 and 77 on GPU2 on a 2 loop valley run at 1125/1700 1.2 volts. This was on the stock fan profile which I think hit around 48% speed max.

Any side fans? Where is all the heat going that the 7990 dumps out? Mine seems to run hotter than that. However that could be because of my case maybe.
Pretty much what i did with my 690. Exhausting hot air was already set and doing it's think, so i just concentrated on getting cold air to the card.
In an ideal world I wish the middle intake was a bit lower to get a bit more cold air over the card but cest la vie! Seems to be doing alright regardless.
This is how my setup is currently. I'm open to suggestions or improvements.
I have 1x200mm at the front bottom blowing in. 1x120mm blowing in above that. 1x120mm at the rear blowing in. 2x120mm gentle typhoon fans on intake in the roof cooling my h100i. Then i have 4x120mm exhaust fans sucking out the heat via the side panel. It works as i can feel plenty of heat coming out. Not sure if i can improve things though as i want to keep a positive pressure and my h100i makes things a bit difficult.
Can all 7990 owners run a test or something so we can compare temps? I want to make sure mine is not running much hotter than others.

I have a side fan exhausting, top two fans exhausting, rear fan exhausting and the front fan as an intake.
Not sure this is the best way but that's how I have it...

That probably gives you the best possible gpu temps i expect but you have negative pressure. Do you find a lot of dust in the case?
7990 users, copy these settings and report back.
7990@1000/1500, Auto Fan speed on 7990, case fans at lowest setting, power line +20%.
Complete one benchmarking run of Valley at the below settings then quit and check afterburner for both gpu temps.

Not sure how accurate that will be to be honest as my pc is about a foot away from a radiator so when on naturally increases temps. Ambients will play a big part, tbh I don't think your temps appear to be out of the ordinary.
I know but i still need confirmation and that includes you old chap.
Just ran another this time undervolted to 1.100v though i doubt this is game stable.
Will run one more now with my case fans at the highest settings at same settings but with 1.200v.
EDIT
Very little change with all case fans on high. GPU1 was 1c warmer and GPU2 was 1c cooler. Maybe i should try making that back fan exhaust. That might give me a negative pressure though.

The top fans are connected to my H100i. If i use that as exhaust my cpu temps will likely plummet. I have that as intake for lower cpu temps and the H100i doesn't kick out too much heat, just a little bit of warm air.
Have to agree I think your temps look about right! Will try and get a quick run in before I go out tonight but if I can't will definitely tomorrow morning.
I am tempted to strip down the cooler and apply some gelid extreme but I've heard the 7990 uses some phase change thermal paste and is not really meant for disassembly unless replacing the entire unit. (Still I'm tempted)

Yes im temped as well mate. Sadly i don't have any thermal paste otherwise i probably would have already. Not sure if theres protection on there either so they will know if you remove the cooler. Don't want to void the warranty.

Pretty sure there isn't remember reading somewhere (overclock.net possibly) that there weren't any stickers when disassembling to apply a waterblock. I know my warranty void stickers are simply on the backplate. Maybe our watercooled brothers can shed some light if there is?
