Corsair 760T dual rad configuration

post #1 of 7
Thread Starter 
Hey OCN members!

I'm currently finalizing my water cooled build and i just realized that i have one exhaust fan in the back with 5 intake fans (2 front and 3 on top). I was wondering if this would work fine for my watercooling build, or would i need to add another exhaust fan?. I heard that mounting intake fans on the top is not a good idea so my assumption is to run push/pull configuration on the top rad to have more exhaust fans. Your help is appreciated.

As a rule of thumb, you don't want to exceed an intake to exhaust ratio of 3:1.

There's usually no issue with the top of a case being used as intake. In this situation, the only issue is that you will have an intake to exhaust ratio of 5:1, which is indeed a bit too high.

On the other hand, you usually don't want to have a radiator used as exhaust while another is used as intake. The reason for this is that after the air has passed through the first radiator at intake, it is heated before being used to cool the other radiator at exhaust. In combination with adding the heat generated by your motherboard and other components in the case, this can severely diminish the cooling ability of the exhausting radiator, since it is using hotter-than-ambient air for cooling.

I would recommend keeping the two radiators and five fans as intake, and looking to see if you can add any more exhaust to your system. Maybe your case has a side panel with a mount for a fan which can be used at exhaust? If not, maybe you can cut your own hole for exhaust? Maybe you can add a fan on the back of your case that will exhaust air through the vents around the PCIe slots? If you have a PSU with a fan, you can flip it over to intake air from the case and exhaust it out the back. If you can try two of these suggestions, you should be fine.

Thank you for your input!. the 760t has a clear side panel which makes it really hard to custom make some fan brackets on the side. however, my CoolerMaster PSU has an "intake" fan that is pointing downwards, so i'll do what you said and flip it over so it can take air from the case and exhaust it through the back of it.

You should be okay with your setup.

You can even leave the PSU as it is. The PSU is drawing air from the bottom and exhausting it out.

The 760T has vents in the back, so with all the air as intake (its pushing air through those vents).

My setup (for both rigs) are all rads are intake and just 1 exhaust fans + whatever vents i have for the case.

Temp inside the case is warm to really warm (at best). But it doesnt affect my components at all.

Well the point of having watercooled system is to reduce those temperatures significantly but if it doesn't really affect watercooled components by much then it's no big deal to me.

With the 760T you've got it made in the shade with some light case modding. Just go around to the back of the case and where the watercooling punchouts are and make your own vent holes with a power drill.

^This is where I'm talking about.

Grab a 120mm fan. Line it up so it's flush with the case edge on the side. It'll overhang the PCIe brackets; that's fine because those already have holes for exhaust, too. Place it as far up or down as you need so it doesn't block anything on the brackets that you'll actually use, drill the mounting holes for the fan, and a bunch of other holes in that general area. If you're feeling particular, you can trace the semicircle of the 120mm fan on the back and draw a matrix to get evenly spaced holes where you need them. Place the fan on the back of the case, plug it in, and bob's your uncle.

Then just flip the PSU to intake air from the case and exhaust out the back, and you're all set!
