Case fans

[Tommo791]

I currently have 4 case fans in my PC. Two intake fans on the side and one on the front, and one exhaust on the back. My GPU runs very hot at idle, and I was wondering if I could put a case fan (I have spare fans) on the bottom of the case blowing directly onto the GPU exhaust. It would be directly below my GPU.

If you have a mounting point and a dust filter, and there's enough space under your case to get enough flow, then yeah go for it. Do anything you want.

The problem is.. My PC case has no fan mounting slots on the bottom of it. The case is a cit vantage type R with a top mounted PSU and the fan would be resting on the bottom (IKR im ghetto). Is it okay to have it inside with no mounting points?

Ah. No that's not OK. It won't do anything. Can you modify the case floor to allow air flow? Or mount the fan a few cm up from the floor using long bolts and nuts? I know it won't be drawing in cool air but it will be more effective than just sitting it on the case floor.

when i had my set up in an antecone case i had 3 intakes fans cm sickleflow with 69.69cfm and 2 stock antec fans as eahauxt still my 7870 was reaching 70-80 on heaven benchmarking

My 5850 reaches 85°C during Heaven. That's fine, that's the cards maximum designed operating temperature and the cards fan maintains it at that temperature once it's reached.

But at idle, it's in the low 30s where it should be. If the card is hot at idle, something's wrong.
