Pump -> CPU or Rad -> CPU

[AmuseMe]

Every where you look, you will find different info on 90-degree fittings. I can't see how OCN says that one fitting equals 4-feet though... Most places I've read said it was like one foot of tubing.

I did little test myself on single loop CPU loop with 3/8" tube on dual TFC rad. Each 90 degree fittings got me aprox 0.1 lpm drop in flow rate. In my books 4-6 of 90 degree fitting in set up is not a biggie at all.

You also always can do dual 45 degree adapters if space permits.

If your using the same 1600rpm sflexs im using, id suggest you should use them to pull air off the rad, and not blow air through. I recently did that change and noticed a massive drop in temps.

How massive are we talking exactly? Because I don't believe the difference between the 2 configurations should be that large; 1 or 2 degree IF THAT. The rad and fans aren't mounted to the case yet so changes can still be made if need be. Can you provide some more information on your setup?

My system specs are on the right and in must sig is my loop. My rad is on the back of an antec 300 via radbox, and the switching of fans brought down temps of about 11 degrees on chip and about 6 on the gpu. But my rad is considerably thicker so that might be a factor in this.
