GPU overheating due to CPU cooler

Hey there everyone. I'm helping someone with a PC that will go completley dead when watching fullscreen Netflix after a few minutes. I have come to the conclusion after seeing that the graphics card ( Old Nvidia GPU) reaches 120*c. I opened the case up and found that the CPU cooler ( Stock AM3 Phenom x6 cooler on Phenom x4 ) blows hot air directly onto the GPU increasing it's temperature. I have since added a 120mm fan on the side panel that blows directly between the CPU and GPU to hopefully cool down any air. I've even added a small cutout of cardboard inbetween the CPU and GPU to act as some kind of Firewall between the two. The graphics card still goes up to 70c-80c on idle and 90c-100c when Netflix is up. Any advice on how to further keep the GPU cool?

I'm confused how this post-1657-0-91437500-1384285810.jpg blows directly onto the GPU?

 

Since the card is old have you cleaned it and replaced the thermal paste?

This sounds like the GPU is clogged with dust as opposed to getting overheated due to the CPU heatsink (Remember heat rises away from the GPU) get a can of compressed air, hold the fan still and blow air into the heatsink of the GPU (Don't hold the can upside down!)

There is no reason the GPU should be 120c.. Like they are saying, has to be WAY dusty. At idle, which netflix basically is, it shoudn't be over 50-60c MAX. And the CPU air isn't that hot either, nothing in the computer should be anywhere near 120, not even near 80 at idle. Dust everything out, and if that doesn't fix it, something is seriously wrong with that gpu :/

Toasty!!! Mind you telling us what GPU exactly, and how long have you had it, and then when is the last time you cleaned it. Personally i think you should be black screening if you GPU went 120c, are you sure that you are getting proper/correct/trustworthy temps. 

 

Spoiler

Case Bitfenix Ghost, Mobo Asus Maximus VIII Ranger, CPU i7 6700K @4.2 Ghz cooled by Arctic cooling Freezer i30, (barely). GPU Nvidia GTX 970 Gigabyte G1 @1519Mhz core, RAM 16Gb Crucial Ballistix CL16 @2400Mhz. SSD 128GB Sandisk Ultra Plus as my OS drive. HDD's  1TB  Seagate ST31000524AS its OEM, 3TB Seagate Barracuda, 2x 500GB WDC Blue (RAID 0)

If it isn't working absolutely perfectly, according to all your assumptions, it is broken.

What is the GPU fan running at in percentage? The stock CPU cooler will not cause the GPU to overheat. There must be another cause - like the cooler on the card needing remounting or the thermal compound requiring a re-apply.

Is your case overall airflow working? Having that 120mm at side intake is good thing, but remove cardboard. It could be fire hazard if GPU pcb really reaches near 100C temps. Try removing side panel and check how fans are doing while under mild stress. There's no way that CPU cooler pointing to side panel is causing this. Heat rises from it to back exhaust.

This^ I'm sure that card didn't reach temperatures like that on day one my friend. A lot of dust-filled air would have passed through that heatsink over the years, clean it out.

I agree this can only be a lot of dust, and install Aida64 (don't have to buy full version) and check the whole system and fan speeds of this machine. And as someone already wrote replace the thermal paste on the gpu.

Depends where you live but you can already buy cans with compressed air for a cheap dollar. So you guys should be able to do that comfortably at home.

I don't think its something with the cpu...
