Help choosing between 240 Rads

post #1 of 8
Thread Starter 
preamble: I have read the skineelabs comparisons on 240/360 rads.. but all the ones in their reports are too wide for my case/mobo positioning.. so I am on my own here, thanks in advance for any advice!

I am building my first WC loop and I need to start with the single best performing 240mm radiator that will fit in my case. I have a 1.5" inside top mount constraint between the mount and the usb mobo connectors and dimms, so max depth = 38mm. In this class, I have narrowed the search down to two rads that are low/med rpm with good watt dissipation.. but seeking input for sure.

Here is what I found:
1. Koolance HX-CU720VS (38mm@20FPI/1.85gpm max) - $45
2. Swiftech MCR-220-XP (34mm@20FPI/ CW drop after 2LPM) - $52
(The Swiftech MCR-220-QP will also fit, but performs lower at higher rpms >1200-1500)

My plan was to just use 1500-2000 RPM low DB/ high CFM fans top mounted outside the case in pull.

Any suggestions or experience with either of these rads, or any others in the sub 38mm profile? Trying to purchase asap.. getting stoked to build!

What about the XSPC EX240? It's slightly cheaper and better performing with the fan speeds you mention. In the 360mm tests, the EX beat the Swiftech by a degree and a half Celsius and the Koolance by nearly 2C delta.

the ex 240 has a better design than both the koolance and swiftech and it runs a few degrees cooler.

I agree, xspc ex series is the way to go for best price/performance for your 1500+ rpm fans

I also agree with the others, the XSPC EX Series 240/360 are better performers than koolance and swiftech radiators!

Hey Guys - Just an update - but I took your advice and got the EX series.. but after hemming and hawing for days, decided to take the risk and try to make the EX360 fit in my CM690II case, and I am so stoked. It fits like a glove.. really couldn't fit another 2-3 mm. I lost my top side x-dock (ext. sata drive bay), and half a drive bay, but I didn't need them anways.

What I love about the rad is that it seems really clean. I am running it now in an open loop, leak testing all the components for 24 hours and so far clean as a whistle. It is hella fragile though.. I bent a few fins just putting it in the case with my hand hitting once. Glad I ran it first thoug cause I bought an EK block for my 5870 and found some leaks where - low and behold - ebay homeboy left out a few screws. I just happened to have an exact match in my screw collection.. an impossible find.

Anyways.. I will post some picts when I get it done in the other forums.

Thanks again!

The fins on most radiators are very soft and bend easily. They are also easily fixed with a paperclip or toothpick.

I too noticed that my XSPC radiators were very clean. I had no noticeable gunk come out of my RS240 or EX240 when I flushed them. Also my EK XT 360 was pretty clean as well, but my BlackIce 120 Steath had all sorts of crap come out of it. Far more than both my 240s and 360 combined!
