Radiator placement

[Sebbe218]

Hey guys, I've got a question concerning the radiator placement in the Corsair 750d case. 

I'm building a pc with the Hydro H115i AiO cooler and I don't know where to place the rad. There is place in the front of the case or at the top, also with configuration is best? Push/pull? Should I have it as an intake or exhaust? 

 

So far I've thought about having the rad at the top with a pull configuration as an intake? - then I'll have the dual 140mm front fans as intake aswell as the top fans so the rad gets fresh air. - But that would also leave the case with only one exhaust at the back (140mm). But to take into consideration... the case is pretty large so perhaps extra positive flow is a good thing? I don't know.. 

 

Anyways thx!

I would go with top as exhaust. Airflow from front intake will have minimal to zero restriction that so your air pressure would still be positive or at least neutral.

If I go with the top as exhaust, wouldn't the cpu suffer from a higher temperature since I'm pulling hot air through the radiator?

Always exhaust on my rigs. Hated front mount but I no longer use aio's.

That would happen if you put the fans as intake, he recommended to put the fans as exhaust meaning pushing the hot air out of the case throught the top.

 

There really is no need for push/pull but if that is what you want just make sure you have the clearance on the top for it and if you do the push pull you would put both sets of fans as exhaust to push the air out of the case.

I've done both in many different setups, and the difference is usually minimal. Most of the time, but not always, you will get slightly lower, maybe a degree or two, by placing it in the front, as you are bringing cool air through radiator. The trade off is, you get higher ambient temps and possibly higher GPU temps depending how it's cooled. If you place it up top as an exhaust, your ambient air will be cooler, but then you would be pulling warm air through the radiator as it exits the top.

 

Personally, I think more important than placement is orientation. Example, if you place it up top use it as an exhaust, or as an intake up front. Me personally, I prefer the front. I generally include the GPU in my loops, so I don't have to worry as much about having Warmer intake air.
