I put a fan on my GPU like this, is it going to affect its temperature?

right now this 7970 is the hottest component on my rig, after push/pulling hyper212 evo with 2 cougars, the noisy assistant fans inside Z87 Sabertoogh's TUF to deal with MB, my highest temp's for this 7970, it usually hit 70 at most when im playing for hours, and it shorten its lifespan im sure.
its Evo's stock fan in there

I've three questions:

(1) does any Intel GPUs like 680 or 780 get hot like this?

(2) whats ur opinion about another option and put the fan below GPU and replace the GPU for the upper PCIe3 slot, or the current one is effective?

(3) GPU-z says the GPU is on PCIe v3 x8 while it supports x16,
the Manual says: 2x PCIe 3.0/2.0 x16 slots (single at x16 dual at x8/x8 mode)
I use only one GPU so why's its showing x8 mode

70 degrees for an hd 7970 isn't much a lot off people get this temprature. also that fan you are useing to "cool" the hd 7970 is helping its better if you put it in the bottem and let it blow directly in the cooler off the card. also your card is really close to the psu i reccomend getting it in the highest slot available. that is probably also making the motherboard think that there are 2 gpu in the system and thats why it puts it into x8 mode (could also be powersavingmode when the card isn't used much). and the 680 and 780 are nvidia card and no these don't directly run any cooler then your card it depends on what they use for cooling it.

Hi
I would move the GPU closer to the cpu if possible.
Then I would remove the fan you have fitted in front of the GPU as most of its output will be pulled through the CPU heatsink by the intake fan.
This fan I would then fit to the intake port behind the power supply this will assist the fans on the GPU.

Hi,

1) yes they do get that hot, and 70C is not even too hot so dont worry.

2) I think you should try to move it to the top slot and that might fix your problem in point 3. And the fan could run nicely at the bottom there feeding the card fan nice cool air.

3) If the top slot is stil 8x then look in the bios it might be set to 8x there somewhere.

I think I remember a test done a long time ago by some cooling experts saying that it is much more effective to push cool air into the box than trying to vent it. In other words it seems you have 2 exhaust fans and only one intake fan. Monitor you temperatures and turn the exhaust fans into intake fans and see if it helps. In tests I have seen the hot air will escape through the holes. It might make sense to leave the top one as it is (hot air rises) but I would test it because I have seen it work better with all fans turned inwards.

thanks everyone
the case is HAF932, three big fans, x2 intaking (x1 side panel x1 front bottom of the case) x1 exhausting at top
I tried All-Intake option resulting in a dust pit for my case, too much dust to deal with, but about side panel fan, its right in front of the GPU when i close the side panels
its intaking and throwing air at GPU right now
i could exhaust air in that area
is it better to take air from GPU or throw air at it?

It should actually become a dust pit with negative pressure i.e. more exhaust fans. I think for the GPU and CPU it is good to blow air onto. Manufacturers of cards and CPU always point their fan onto the chip itself and I remember reading that it is much more efficient that way than trying to pull the hot air off from the surface. Also you wouldnt want to create negative pressure above the intake fan of your GPU by sucking air out.

thanks, ur replies seriously helped me alot, the lower PCIe3 slot was x8 permanently, not in any power saving features and...etc, but the upper slot is x16 while the Manual is saying both are x16 anyway

i mounted the fan at bottom and its apparently way better than before, but I've a question about 212evo, when u mount a fan on it, there's a 4/5mm space and gap between them if u look at my pictures, i use a white sticker to cover this gap, the sticker will surely loosen by time,
sorry to ask questions again but i've two questions here

(1) does it make any difference to cover the gap or not?

(2) do these Intel Rapid Technologies, are necessary? (storage, connection, start)


I mean 5 or more second boost in start up doesnt really matter for me, and i dont RAID or not a fan of Emails and facebooks twitter
