I don't recommend getting two 240 radiators unless you really need them, it's just too expensive for the gains. One issue with the various Reserator systems is the combination of aluminium and copper. In a system with both metals an inhibitor becomes necessary. Zalman provides an inhibitor, but if y...

If you have space for one, you may consider getting a triple fan radiator. They tend to be only slightly more expensive than the dual fan radiators, and provide 50% more surface area. More area means lower fan and/or pump speeds.

My D5 in stock config (I bought an aftermarket mod) at about half power was about as loud as an 600RPM - 800RPM S-Flex, but lower, more midrange, with a faint very high pitched hiss. At full power it had a grumbling noise and a lot of vibration, but at half power it wasn't too bad. The aftermarket m...

The real problem with the XSPC kit is the loud pump. You'll have to replace it with a quieter one, and that will make the end cost higher than just buying custom. A D5/MCP655 is about $70 Cad. Primochill tube is about $20 Cad for 10'. An MCR220 radiator costs about $60 to Cad (don't know if it's ava...

If you have a corrosion inhibitor you can mix copper and aluminum, but I don't know how well it would work or for how long. It would likely be easier to get a standalone radiator. It would also be easier to get a copper/brass radiator than it would be to find an aluminum water block, but if you have...

The Liang DDC/Swiftech MCP350 is reported to by a pretty quiet pump. I haven't heard one myself, though it's supposed to be quieter than a D5/MCP655. Swiftech reports it to be ~25dBa @ 12v, and it can be undervolted to 8 or 9v. Your radiator isn't really a good choice for low fan speed operation, to...

Pretty sweet, I especially like the wood box/stand. Very classy looking. Does the rad have any fans or is it fanless?

My only complaint is that it's apparently an aluminium radiator. I personally prefer copper/brass because of galvanic corosion, but you've probably added an inhibitor for that.
