1 140mm rad enough?

[Uwillparish]

Hi guys,

 

I own a corsair 300r case, And am thinking of water cooling it(open loop), Now if you look at the case you will see there is almost no room for a 240mm rad up in the top, so the next place i would be able to put it is above the drive cage, Which is a 140mm fan slot, But the problem is i want to water cool both my GPU and CPU(gtx 970, Yeah i know, VRam, And i7-4770k) But from what i hear 140mm rad aint enough to cool them enough. What do yall think?

In Australia, normally we say that a fan per processor + 1... But then again it is currently 30 degrees at the moment

140mm would be enough for just the CPU or the GPU but not both.

No definitely not enough. I'd say the minimum is a 360mm radiator.

You'd be better off with an AIO for the CPU and an aftermarket heatsink for the GPU like the Gigabyte G1, EVGA ACX, Asus Strix, exc.

Terve!
I do think that this can work, but your temps won't be good.

I would go liquid cooling on an other case, where you can use more RADs or I would completely skip it.

The GPU should not be overheating, if you have a good coller on it and a Noctua would cool your CPU perfectly.

With the 170mm you can put in there, you can use a NH-D14. But be carefull, the RAM slots will partially be overhung.

If you do not need the top PCI-E Slot you could use an NH-D15 and save the space over the RAM.

I do not recommend AIO, since you have more parts that can fail (pump, tubes, RAD, Block).

Also a 4770k could be cooled by something smaller, it just won't be as cool as the AIOs or the Noctuas.

Hope I could help you.

Yeah a single 140mm radiator certainly won't cut it if you're wanting to do both the CPU and GPU.

 

One thing you could consider is finding a way to externally mount radiators and then run tubing out to it. I participated in a thread over on The Mod Zoo forum regarding someone also asking about building a loop in a small mid-tower case.There are other options available to get the radiator capacity you need -- it just might require getting a little creative.
