Swiftech Storm Review @ OC.com
http://www.overclockers.com/articles1261/
Something's terribly wrong though. The pressure drop is drastically high according to Joe. According to Swiftech's own data here: http://www.swiftnets.com/assets/imag...%20vs%20fr.gif The pressure drop at 1gpm is ~1.65PSI. Robotech @ SystemCooling.com reviewed the block and measured the pressure drop to be as follows: http://www.systemcooling.com/images/...image21big.gif or around 1.5PSI @ 1gpm. My own data puts the pressure-drop of the Swiftech Storm at ~1.53PSI @ 1gpm. Robotech and I were measuring with 1/2" OD barbs. I suspect that Swiftech's values are perhaps taken with 3/8" OD barbs. Joe's data puts the block's pressure drop at a staggering 2.74PSI @ 1gpm, and WAY out of line with 3 other measurements. Was JoeC's Storm block heavily clogged during his testing? His results for it were a little disappointing to me, even though it handily took the lead, and I strongly suspect that cloggage may have something to do with that? BTW - I had already emailed JoeC, but wanted to raise this here too as I think it's a valid concern. |

Looks more like a full system pressure drop Quote:
Using MCW6002 as reference, there maybe no problems: |

I'm not saying that JoeC's thermal measurements are WAY out of whack, just perhaps up to 0.01C/W out, which could be accounted for by way of clogging causing the increased pressure drop. |
