MCP655 power

[magictorch]

Is one MCP655 powerful enough to pump through 1 MCR220, 1MCR 320, 2*EK GPU blocks and 1 Apogee GT block?

Seems like a powerful enough pump but I could do with some enthusiast opinions.

get the vario version of D5

yes but need to use a res in loop to feed that pump

D5: 3.1m head with 1200lph
D5 vario: 3.5m head with 1200lph

what size of tubing will be using?

Seriously, those EK GPU blocks are brutal for flow restriction, just like the EK Supreme CPU block. Yeah, the pump will probably manage, the blocks are good, but your flow is going to be hurting. If you're running two GPU's, you might be better off running MCW60 or Fuzion GPU blocks instead.

I agree with MpG, it's going to be brutal with the 2 EK GPU blocks. You are better off splitting the loop in two and toss a extra pump. If not, get the MCW60 or Fuzion GPU v2 (note the v2, the v1 is also brutal in terms of flowrate).

MpG, how about running 1 EK GPU block and an Apogee GT with a MCP655, would it also restrict flow or am I going to be fine, I am looking to upgrade the cpu block (either before I build the loop) or sometime coming soon..

Thanks.

Sorry for threadjacking but I was going to get the EK full cover waterblock for my 9600 GT. From the general censes it looks like the Switftech block is better. My only question is what ram sinks should I get for my ram and mosfets and how many packs. As well what is the best thermal tape to use?

[magictorch]

Balistx Id recommend the copper enzotech ramsinks as they come with a good sticky thermal pad and are of high quality.

As for the EK blocks, Blackice has assured me hes shipped the pump I bought at his FS thread so I should have the extra MCP655 pumps by next week- =one for the GPU loop and one for the cpu loop.

I think an MCP655 will be fine for 1 rad, an EK GPU block and a cpu for anyone looking at that.

I used MCP 655 for dtek fusion, blackops block, 2x3870x2 blocks, Maze4gpu, swiffy 2x120 rad, BIP120, and BIX360, both with t-line and res...takes forever to bleed sucha loop with a t-line! end flow put out about 2-3 litres per minute, probalby dropped flow by about 2/3rds.

[magictorch]

Cadavea what were your temps like? As long as you've got half decent flow temps itshouldn't be too bad? I need to read up on this though as MPG and Xilicon werent impressed with the idea of multi blocks and rads with a res with one MCP655--

[cadaveca]

Yeah, I wasn't much impressed either...I got almost 10c lower on everything when I split the loops to cpu/chipset, vgas/physx. It WILL work, but no, it is NOT ideal.
