adding a 240 clc in a corsair 600q case

[davegv]

I am going to add a evga 240 clc water cooler in the bottom of my case. I have read mixed ideas about me wanting to place the cooler fans blowing air out of the enclosure as shown in attached pic... It seems to make more sense than the radiator blowing hot air onto the cpu and gpu as it also provides another air exhaust/outlet. the case has two 120 front fans and a 140 exhaust. I am interested what others think? Thanx.

The radiator as a front intake will have access to the coolest air and have minimal airflow restriction (at least in theory; that case has a very restrictive front panel), but it will also heat the air coming into the case, which might increase VRM and motherboard temperatures (though not enough to matter) and definitely increase GPU temperatures. The bottom mount will have access to warmer air (at least partly warmed by the components in the case) and will likely have severely restricted airflow due to the proximity to the floor, so it's CPU cooling capability will be a bit worse, but it won't heat anything else. In short, it's a tradeoff between better CPU (front mount) and GPU (bottom mount) temperatures. Pick whichever you find the most important.

Mount it on the front.

Some of that heat will build up anyway simply because the hot air will tend to rise. Honestly there is no good solution for that case, what an odd design.

Given just how incredibly weak a force convection is, even the slightest gust from a fan will overpower it. There is still a risk of a "bubble" of hot air on the top around the GPU, but that is more due to proximity to a hot GPU and the lack of an exhaust there than from the air rising to get there (particularly with GPU fans pulling air down from that area). A good fan in the top front will cause enough disturbance to mostly break that up (causing enough circulation for a lot of that hot air to go out the rear exhaust fan), but a blower GPU is likely the best cooling solution for a flipped layout like this. I guess if the PSU fan is pointed inwards it will also help exhaust this hot air, though of course that will increase PSU temperatures.

@Valantar Thanks for the replies - always good to get another's view. I am going to put it in the bottom and possibly add another set of fans as shown in this build ( attached Pic ). I have a GTX1080 in this system and it remains very cool even at 100% Load ( rendering, ect ) Just want to replace the stock Prism wraith on a 3700X Ryzen.
