I'm trying to come up with my own custom loop, I'm looking at:
-Pump: Swiftech MCP655-B
-Block: EK Supreme HF
I kinda picked whatever is best, I have no idea about the rad I should take. I also have no idea on what size of ID barb I should take. This is going to be a CPU loop for now, one day I might extend it to GPUs so I don't want a weak pump. Then again I don't know the physics behind watercooling, perhaps too much pressure if the pump is too strong and the loop too small = leak.
Considering I was originally gonna go with an H70, I'll definitely get the Rasa 360 if I get a all in one kit.
Get the non "B" MCP655 pump. The B is fixed speed, whereas the "Vario" allows you to choose your speed up to 5, the "B" is stuck at the 4 speed.
That block is the top of the heap, the Rasa isn't far behind and is generally $20 or so less. Up to you and your budget.
You're going to want a rad, reservoir, tubing, fans, distilled water, and some kind of kill coil/biocide to prevent organic growth (algae) in your loop. Radiator choice depends on space in your case (or outside if you wish), if you plan on adding your GPU's to the loop in the future, how quiet you want the system, etc.
If just cooling the CPU, you should be fine with a thick 240mm rad. If looking down the road to increase your loop (GPU's etc) then you may want to look at a 360. People like the XSPC RX series of radiators due to the low FPI which doesn't require high RPM fans for optimal cooling, keeping the noise down. If you want pure performance, you should look into getting the Black Ice GTX series, though these require high RPM fans (1800+) to obtain the best cooling. This set up of course comes with a hefty noise increase over the RX radiator + slower fan.
A lot of people like the Gentle Typhoon series of fans as they're fairly quiet (no ticks, clicking, harsh motor noise etc), have high quality bearings, and high static pressure to push the air through the rad. There are a few different RPM varieties, the most popular being the 1850 RPM (AP15) as it has great pressure and CFM through a rad, yet can be undervolted very easily to be silent. They are a bit pricey at $16-20 each. A cheaper alternative would be Yate Loon fans, apparently Petra's Tech Shop (PTS) and Sidewinder sell the best quality ones (better/quieter motor, optimized fins, etc).
Check out martinm210's fan comparison videos to see how different fans perform and sound pushing through a rad, including a few PTS Yate Loons and Gentle Typhoon fans.
Any reservoir will do the trick. You can choose the functional bay res types, which only uses 5.25 bays rather than other space in your case or something flashy like the T-Virus res (expensive too). Get whatever you think looks good and will fit in your case. You just want the res to be above the pump and feeding into the pump inlet.
The pump already has 1/2" barbs, so you probably want to stick with 1/2" barbs (or compression fittings, more expensive) and 1/2" ID tubing. People recommend the PrimoFlex tubing found on Amazon at $16 for 10' or so with free shipping.Edited by whiteslashasian - 5/12/11 at 12:21pm
