GPU very hot in one computer but much cooler in another

I've come across an odd experience.

I want to try to keep this as short as possible.
I temporarily moved my hard drive and GPU (gtx 960) to another computer while i was modifying my main pc. while playing games on the secondary computer, i noticed my gpu temperatures would stay under 65 degrees Celsius compared to my main PC where they would always be around 80-90 degrees C.

I don't think it has anything to do with airflow because the cases both had bat airflow. So why were my temperatures so low in the temporary computer compared to my main one?

Specs in main pc: i7-4790,gtx 960, 12gb ddr3 1600, and some acer motherboard
specs in temp pc: i5-4690, gtx 960, 8gb ddr3 1333, asus H81M-K mother board.

You don't mention the load placed on the GPU. Maybe your primary runs it at a higher percentage of use? Another consideration, besides airflow, is how much heat the other components put out. If the secondary PC generates less heat from its other components then the card will have a cooler environment to start with.

bad is relative

his case may be bad, but still be a lot better than your bad case

fan placement also matters a lot

I didnt check how hot the i5 cpu was running by my i7 is also always running very hot around 80-90 degrees C

at those temps the cpu is most likely also thermal throttling leading to your crap performance

you either need to buy some case fans or a whole new case altogether


those temps are not good at all

Yea, i just ordered some extra case fans. Hopefully those will make a difference
