[SOLVED] 3 top fans slot, 1x 240mm rad top mounted

[worstshire]

Hi guys,

I am wondering one thing here:

PC Case is Azza Inferno 310. It have 2x 120mm front intakes fans and 1x 120mm exhaust fan at the back. There is place for 3x 120mm fans at the top and i want to put my 240mm radiator on the top pulling fresh air in, but i know its not ideal for the GPU cause it will push hot air on it. So the rad will take 2 slots from the top so one slot is left for 1 more 120mm fan... I am wondering if i put the 3rd fan as and exhaust would it make sense? So the 2 top fan on the rad pulling fresh air in and the 3rd fan will exhaust hot air. The top exhausting fan will be mount near the exhaust one in the back.

Sorry for my english

Any advice would be really appreciate!

Your pc should look something like this. If top mounting the radiator, it's used as exhaust. Gpu heat is negligible when determining that, won't affect cpu temp at all. Do not use top mount as intake, it dumps all it's heat inside the case and there's not enough exhausted airflow to really remove all that.

But my GPU is running kinda hot, its a 1070 ti from MSI and my CPU is a 9700k. So you think that pushing the hot air (generated by the GPU) from the case true the rad won't affect my CPU temp?

Nope. If you put the rad on top as intake, all that exhaust will head directly to the gpu, straight down, pushing all the gpu exhaust right back on itself. The front intakes will supply the gpu with air, the top exhaust will remove the gpu exhaust up and out.

As long as you have decent in-out air flow then you'll be fine as far as cooling goes. As to exact temps, that's going to be on the gpu/cpu loads.

Just having that extra exhaust can drop your current temps as much as 10°C or better as that single 120mm exhaust prolly isn't adequate to the needs with that gpu.
