Mine goes more than 80 degrees until I learn how to configure the fans of the GPUs to run at a constant 80%.
If you use CGminer, you can configure it to have a target speed and control of the fans.

nothing about about 64 at the very highest.
you cen gett good cpu and gpu chip only blocks faly cheap
What is fairly cheap and where are they sold?
Link or it don't exist.
A gpu only block looks no different than a cpu block. I wouldn't recommend it due to the pain in the ass tube routing you have to do. Also you have to get heatsinks for the vrms and ram. I'd recommend a full cover gpu block instead. They cost more but the convenience is worth it.
Still, seems like a cheap CPU block is well over $50. With a 3D printer and a copper-plate that can most likely be reduced to a fraction of the cost. (Not minding the cost of the printer itself.)

You may have your reasons, but I think it seems strange to have a watercooled CPU in a mining rig...
Are they all like that, or did you convert a previous build?
i just dont have a cpu heatsing and backplate for that motherboard lol also its my gaming pc / test rig
Then it makes sense :-)
I am waiting to make a combined mining/gaming rig in the basement. Just waiting for the extention cables and risers. ;-)
If I had access to a CNC, I would probably have made watercooling for the CPU/GPU's
Hmm, when I get a 3D printer(sometime in the future), I guess it should be doable to make DIY waterblocks using small copper plates glued together with printed top-parts. -But that will be another discussion

i udervolteed a bit, now is 66° with 50% fan at 28 ambient T
For me, a 5mhz increase comes at a sweet spot where it comes with a 5°C increase. Go from 1000 to 1005 on the 7970 and it jumps from 83 to 88. Not good.
However, AMD says these things run stable at 90-92 as maximum temperature target. They are supposed to take peaks of 105. So 85-88 should theoretically not damage them
Could you link us to some readable material from AMD? However, AMD says these things run stable at 90-92 as maximum temperature target. They are supposed to take peaks of 105. So 85-88 should theoretically not damage them
I use 2 sapphire reference 7970 on my Water cooled system, so mining Bitcoins i got 720/730 Mhs in --gpu-engine 1180.
My temperatures are allways under 60º (44º-53º).
Also have 12 5830s, they are just runing with air cooling system so they are in --auto-gpu 68º all time, nice fan speeds.

I typically set my target temperature at 70, overheat at 75, cutoff at 80. I use a window fan to cool each rack of six cards ($25 at Target, worth it).
My cards are overclocked to around 1200 MHz, too.
My cards are overclocked to around 1200 MHz, too.
the fan must use like 40w i only use 3 x 1.2w 120mm fans per 4 cards
It does use a lot, but the 120mm ones I've tried couldn't move enough air. Temps were too high for my taste...

I still think of it as a badge of honor(or stupidity)but 2 weeks ago,I left for the weekend with my Gigabyte 7950 running at 102 degrees.
And yes,it survived.
Now that I've learned my lesson,I'm running both my 7950 and 7870xt at 70-80/60-68 degrees,depending on whether the ac is turned on.

I'm running 2 Sapphire 5870 1GB. GPU0 and GPU1 undervolted at 1.150v and 1.175v.
This lets the top card run 5C less hot, and both are running at 70.5C.
Pretty decent overclock on both cores at 960 MHz and both MEM underclock at 300 MHz.
Getting a stable 427 MHash/s on each in cgminer.

damn thats a lot of 7950s
what type of 7950 do you run?I have the plain old cheap sapphire 7950s and I can't hit 630kh until I am at 1075/1600 on my clocks. Same voltage and I am getting 1kw/rig now, I had them at 1.1v and was pulling 1150w, so thanks for that lol
i have saphire vaporx dual bios oc edition cards i use reaper to mine if you would like to know the setting i use pm me
i have found with the cards im using mem clock makes very little difrents but uses loads more power ( i mine scrypt )

It really depends on system, motherboard and card. I mine at 67C all the way up to 88C per card.
AMD says these cards are meant to handle up to 125C.
I've seen them run as hot as 96C before shutdown. Absolute Max I'd run a card is up to 91C...even then i'd use caution.

mining ltc is not summer frendly, 79-83C
This. I moved back to BTC for the summer - 21C outside, all windows open in house, computer room was sitting at 34C overnight when mining LTC!
Stays below 28C doing BTC, and saves 200W at the wall. 
mining ltc is not summer frendly, 79-83C
Sapphire HD6970 @ 75C
Asus HD7850 @ 74C
Gigashyte HD7950 @ 69C
All cards in a well ventilated Define XL R2.
Just pulled the HD5870 which ran at 92C with fan at 100%. Saved 150W at the wall too. Fan is OK and heat sink is clean. TIM replaced recently. I think it's just f**ked.

2x7950 in a computer case tend to run around 70-74C and get 590kH/s on 989 Core Clock and 1479 Mem Clock, but I undervolted to 979mV. Undervolting is magical, without undervolting one of the cards hit 96C, which was way too high for my liking...
Mine are voltage locked so I'm up shit creek in a manner of speaking. In saying that, I CBF reflashing to a different bios and seeing as having one card in at a time doesn't go past 70C, I'm keeping fingers crossed that these risers will help me out somewhat in spacing the cards out more and allowing more air to flow around them. Had a constant temp of 65C last night given it was a rather cold evening and the lowest I got was 59C...
These are the Ghz editions non reference I might add.
Edit: Argh didn't read you stated 7950, thought it was 7970 - My bad

2x7970's in an open case 4x120mm fans blowing straight on them and card fans @ 85%. When sandwiched together, whichever card I have in the top slot rockets to 100C easily and would keep on rising if I didn't stop cgminer. The bottom card in this configuration only gets to about 75C. On their own they comfortably sit between 60-65C, so I'm waiting on powered risers to arrive so I can hash with both the cards again instead of just the one. This should hopefully solve my cooling issue or at least stop the insanely high temps.
Mostly 95C but a couple of 7950s run at 100C. Not good I guess and the weather is only getting hotter!
I would not be surprised if those burn out before you make ROI.
73-74°C at 100% fan speed. Is this risky?
The lifespan of your fans drop dramatically running full tilt like that. I keep my cards around 75%, temp is ~78C. During winter months I get sub 70 C...
My 7950's all run 64-68C with the fans at 75%. Running at 1185 core, 200 mem, 1.08V.
Mostly 95C but a couple of 7950s run at 100C. Not good I guess and the weather is only getting hotter!
Wow! How long have they been running like that? I wouldn't expect they will last more than a few months at those temps. Maybe try undervolting or reducing clocks to keep them below 90C?

Overclocked, running at 78-85 degrees depending on ambient. 3+months no problems. Consensus seems to be this is a little too hot.
I have 7950s undervolted/overclocked with fans at 60%, they hover at 59-60c
Just got back from returning a 6970 that idled at 80 degrees and jumped to 100 less than 2 seconds after cgminer starts up.
My 7850's stay below 70, though.

Have a friend his GPUS run at 90C ..then again one of them blew up too...
anything over 80 is a iffy idea...

How hot do your GPU's run? I have a 7950 WF3 it is running at about 67c with 70% fan speed. How hot do you think is too hot?
