What size radiator do I need for a CPU only loop?

post #1 of 12
Thread Starter 
If I were to watercool only my 2600k clocked to around 4.5-5ghz how big of a radiator would I need?

2x120 max. I recommend the RX240.

I usually see on here that 120 per component underwater. 240 would surely be enough for a decent OC

Pretty much this. You can make do with a good 120, but I would recommend a 240. Any more than that is overkill thumb.gif

It depends on your goals and available space.

If is a gaming rig, and a little noise doesn't matter, a 120x240 is plenty.

If you want ultra quiet, with low speed fans, or good cooling under harsh conditions, like folding in high ambient temperatures, you will want more radiator.

Because of the overclocks you are shooting for, the step up in cost between good cooling for a gaming rig, and "ultra quiet" or "harsh conditions" cooling can be quite significant.

Fair warning, this stuff can be addictive. Once we get started, most of us end up going way WAY over our starting budgets chasing just 1 or 2ºC better cooling, and/or lower sound levels. wink.gif

Man isn't that the truth

Since when are we concerned about overkill on OCN biggrin.gif

All joking aside 120 will be fine but I say 240 so you don't have to listen to fans at full speed. Everyone gave you great advice

a nice 120mm will be plenty but if you want to and have room a 240mm rad would be better.
