Radiator Front or Top?

[KhaderKh]

Hi,

 

Currently i have the Radiator on top and fans as push, therefore acting as exaust and sucking all that hot air from the GPU.

 

Thinking of moving the rad in front and fans as pull to have fresh air from outside but im tentative since its be blowing warm air into the GPU?

 

I'll have 3 exaust fans on top instead of the radiator.

The multiple threads of yours regarding detail questions makes answering actually harder because nobody knows what info you already have received.

 

Use the best vented spot for the radiator. The rest doesn't really matter. Yes, having the radiator as exhaust will heat up the insides of the case less but when you have GPU and CPU on water all other components are basically ignorant to smaller increases in case temps. VRMs with some airflow over the cooler are more than enough in most scenarios (actually, those coolers are often enough more or less pointless - they look cool which is why they are on most boards). If you have CPU or GPU on air (why? if you go the extra mile to do a custom loop, watercool both. If you only watercool one component then go for the GPU, since CPUs are by far less sensitive to heat), then exhaust is the better option.

 

It does not matter whether you exhaust at the front or the top or the bottom. Yes, hot air rises but you have a hugely turbulent system within your case and the force of even 1 solid case fan greatly outmatches the force of hot air rising (just think of it, one 120mm fan moving 90-110m³ of air per hour at max speed, that's ~100,000l of air per hour, about 1,667l per minute or ~28l per second - an average case has an overall volume of ~40-60l so that one fan could exchange all air within that case roughly every 1.5-2.5 seconds - a rough estimate obviously that depends on restriction, airflow paths, etc) .You need to plan your loop in a way that all components that need airflow do get some airflow.
