Front or top mounted AIO?

[Chucky-007]

So as the title says I'm wondering if there's a big different in front or top mounted AIO? by that I mean in temperature difference. I bought the Cooler Master td500 mesh and it comes with 3 intake fans in the front and I bought a Corsair H150i(360mm AIO). I'm also buying a MSI ventus 3070 3x OC. And I bought an extra fan to put in the back for intake or outtake. So should I mount the AIO in the front or in the top for best cooling, or what would u guys do?

I'm a fan of the front mount, main reason being pulling in fresh cool air vs exhausting warmer air.

Up top if you can fit it with the motherboard installed, otherwise up front. If you have another set of fans up top top to exhaust, the difference is negligible, maybe 2 degrees. The GPU will get a bit warmen if you mount it on the front but not by much.

It's personal choice most of the time. The temperature difference is negligible, as seen in the picture below. 

 

However, given your GPU has an emphasis on a blowout design (out the back), I would personally mount your radiator on top. From your 3 intakes, very little of the cool air provided from the top intake will be affected by the GPU or Mobo. It's a shame your case doesn't support fans on the bottom, as it would have been great to have an intake for the GPU. However, that would likely cause a neutral pressure, or possibly even negative.

Is the MSI ventus 3070 3x a blowout fan?

I briefly looked at the holes on the back of it. 2 of the three fans appear to be a blower out while the furtherst right is a blower up, is it not?

Not sure. But should I put the AIO on the top of the case then? And should i use the one fan in the rear as a intake or outtake? I apolagize for asking many questions

On the basis that the GPU is mostly blowing away from your radiator, then I would top mount. For your rear fan, it should be an outtake, however, that would give you a negative pressure system, 4 exhausts and 3 intakes.

yeah but wont that just mean that there is more hot air being pulled out, or am i wrong?

I would have a google of it mate. In some cases yes, but what you will always have is air being pulled through areas which are not filtered.

hmm okey, but what if i use it as an intake fan? i know it probably dosent have a dust filter in the back.

I've never tried it honestly. In my head of CFD, it would create a positive pressure and would only feed cold air to the radiator. My advice would be to try different ways around and put your system under a sustained load using some software. Fans are easy to flip around. Just monitor what your max temps are.
