anyway the temps was around 85-86, these cards shouldn't handle those temps without problem?
Oh, I never go above a very conservative 65°C core temp on any of my cards. Mainly because if the core is 65, the VRM could still very well be around 90°C and I'm planning to use the cards for a long time. That's the issue right there. The VRMs do not normally impact on fan speed directly (at best, only by residual heat transfer to surrounding area, thus raising the overall cooling demands). These are usually the 1st to 'die', not the GPU core or RAM. For mining, or in other words, long periods of gpu operating at the highest clock, I personally keep 60°C as my limit (on 750 TI's). With a previous 770 I didn't have much of a choice though, the best I could ever keep it at while mining, was some 65°C. Cheers, ~ Myagui

for amd if you remove auto(on msi afterburner) and set the fan at low as possible, they still go up if the temps are in the warning zone, why with nvidia it isn't the same?
Not sure why your cards are running so hot. They shouldn't I think. Mine are between 58C and max 66C and I live in a tropical country where the average room temperature is 30-32C. 280X can easily go beyond 80C but I always tried to keep them at 71C - 75C.

Single fan VS Double fan ? no mine are double fan as well, not sure what you guys are mining but xcn make the gpu run very hot, also there are only 2 cm of space between them

Mining XCN as well - 50/60C is hardly a hot GPU - The 2 cm is your issue and why your card burnt! Heat is accumulating excessively and the GPU fans are only making things worse because they are sucking the heat from its closest neighbour and blowing it back into the GPU. 86C for this card is way too much and you are looking for trouble again. You should at least blow a fan in there to dissipate heat. The issue is not the coin but your arrangement. There should at least be a 3 inch space between each card for proper ventilation.

Single fan VS Double fan ? now mine are double fan as well, not sure what you guys are mining but xcn make the gpu run very hot, also i have only 2 cm space between them I have close GPU's too, but I just strategically layed some fans on top of them to blow air between them ^^" 45-55°C, ambient is 15-25°C. Also, I myself will sell my 760 and buy an 880 from the moment it's released. I won't sell my 750ti's though, I still have a purpose for them (casual gamer-friends want one and I want to build a strong HTPC, perfect GPU for that). But the 760 is too underpowered for my wishes ATM, but so is my CPU, but that is a cost for after that ^^

i would say the 2cm is the issue, i have over 5cm between my cards, and here are my temps from no card infront, to 2 cards infront
40'c
45'c
55'c

no it was the 33% fan speed, trust me, now i'm at 67° with 46%, try to lower your at 33% and you will see those 750ti don't need a lot of space, they need just 60w at best, they are not a monsters gpu like 280x-290

my card are around 1cm apart. I got no problem with heat. I am running 6 card rig. I got more than 1 rig. None got any problem. All rig using 750 ti.

Better to keep the fan at auto then. the point is that with amd, if you remove the auto, and the temps get critical, they still force the fan rpm(i tried it with my old 280x) basically this has cheated me...damn..always auto from now, the link(custom fan speed) is also broken., maybe the last msi verison is bugged or something

And the ambient temperature is? And you have air flow?

And the ambient temperature is? And you have air flow? Temp around 58 - 65 (Depending on algo). There will always be 1 card which run very high temp, the rest is low. I am using natural air flow. No fan. Just wind from outside.

These gtx 750 ti aren't really noisy at all, trust me I used to sleep with a 5 X HD7950 rig with fans at 90% in my room back in december

Yep, a few weeks back I was sleeping a few nights in the same room with 3 x 750 Ti rigs and the PSU's were waaay louder than 3 different brands of 750 Ti's (Gigabyte, MSI, Asus non-OC).

I got PSU problem too. I realize that running PSU over 60% create a loud fan noise on PSU. I immediately change it to high watt. Lesson cost money. Running more than 1 rig with loud fan noise will make a person crazy. All of them add together create a jet engine ready to take off
