Crossfire 6970 Water Cooling

post #1 of 14
Thread Starter 
Im new to water cooling and have been looking for a rad that would cool two 6970s in crossfire(I will be overclocking some). So far iv been looking at the Swiftech MCR320-QP or Thermochill PA 120.3 I know the Thermochill is better but if the swiftech is good enough to do the job the price is much better. Also what temps am I looking at with either rad if anyone knows?

The xspc rx360 is comparable to the PA 120.3 but at a big discount. The Swiftech is a normal, non-low noise rad (though they call it low noise, it looks to have a pretty high FPI) but it's pretty cheap and a good buy for the performance you get.

Ask yourself, low noise setup or not? Fancy low noise setups cost more, or atleast the rads do.

Welcome to the forum!

I would avoid the Thermochill PA rad for two reasons; it uses G3/8" threads instead of the almost standard G1/4" and the flux is a pain to get out.

To be honest pretty much any 360 rad will do the job with medium speed fans (1400-1800rpm). If you are running a high noise rig look at the Black Ice GTX rads, they do really well with high speed fans. Otherwise go with whatever good quality rad fits your budget.

For a comparison of a bunch of 360mm rads have a look at Skinnee's 360mm rad roundup.

Thx of the welcome!

The xspc rx360 looks like a really nice rad, also would work well with quite fans. I think it is exacty what im looking for.

I have been looking into how I could water cool my cpu(i7 960), would it work to just put in another rad in the same loop or make a seprate loop? Im trying to keep everything internal so just getting one big rad would not work.

Would a 120.2 rad work? The cpu is going to be OC. I dont plan on WC my chip set, from what iv heard it is not something that really needs it and would not give much to preformace.

A 120.2 would be fine for an OC i7. And the xspc RX series are great rads.

The Swiftech is an awesome choice and the cheapest of the ones listed. It will provide excellent cooling power (more than you need, you can add a CPU on it later if you want) and it will be quiet- it is low FPI and low noise.

The RX360 kit from jabtech could do all 3. Then later you could upgrade your pump/res for higher flow.

Swiftech MCR320-QP is 14.5 FPI.

RS360 is 13 FPI, XSPC's el cheapo normal rad!

Pretty similar no? 15 FPI or so is normal. On the flip side GTX is 20FPI.

The RX360 is 8FPI, PA120.3 is 10FPI. Which one has the least FPI?? Which one will have highest airflow thru with least air restriction, ie noise?

Was thinking the Swiftech was closer to 10, my mistake. I have 4 MCR series rads, 2x 320s and they're all free-flowing and quiet though.

It's a marketing gimmick, adding the QP at the end when all the rads from that family are 14.5 iirc.
