Should I move my radiator?

[A Silver]

At the moment I have my Corsair H100i V2 at the front of my case blowing hot air in to the case and for the most part it is fine but last summer my GPUs were thermal throttling. The main reason I located the radiator at the front was because the PC sits under my desk and I was concerned that it would blow hot air at me if I put the radiator at the top as an exhaust. Is it worth moving the radiator to the top and using it as an exhaust and if so do you think the hot air coming out would be an issue especially on hot days?

Yeah, try it and then you'll know.  It should lower the GPU temps a few degrees, but only testing will prove this out.

 

Maybe move the PC to the desk top?   Sounds like you're not getting enough airflow with it under, as GPU's shouldn't throttle with a decent case.

So long as you have ample intake airflow, have radiators as exhaust is always best as it means they will not be pumping hot air into the case for re circulation, be it into air cooled GPU's or other rads.

 

i for example have 3 240mm rads in my case all exhaust, with 5 other fans as unrestricted air intake.
