For my single loop, i have the pump attached to the res, from the res to the CPU, the CPU to the Rad, then from the Rad it returns to the res...

i just read that i might bet better results if i put the res to the rad, and the rad to the CPU then return the cooland to the res..

is that true? or does it not really matter with just a single loop?


thanks!

It might make a ever so very slight impact, atleast for the first few min. The temps tend even out throughout the loop pretty quickly on a single cpu only loop with a tiny res like that though so overall no real reason to.

Better off with whatever gives you better tube routing. Less tubing with softer bends will be a thousand times more important that the order in such a small loop. (ok not really 1000 times but you get the idea).

Always try to have Your Pump Just before the Rad as the heat from the pump would be somewhat cooled through the rad. And always have Rad just before the cpu or/and gpu WB.

Also res is supposed to be at a higher altitude as your pump.

What i have is MPC355 w/ xspc Plexi top going into XSPC RS360 rad then EK Universal CPU block which then goes to Bitspower res and then it completes the loop going back into the pump.

All this is housed in my CM 690 Adv II

Hope This helps

Order has almost no impact whatsoever on a loop with such little liquid in it. There simply isnt enough time between circulations for the liquid to cool and heat significantly.

The heat from a pump is insignificant unless your pump is so hot that your are melting the impeller into the coolant.

Im just assuming based on what he said, but he is using a pump top with a built in res. Which is perfectly fine before anyone tries to tell him to get a "real res".

A bigger res would allow more time for the liquid to move through the system, and more liquid to absorb heat, but in time the results would even out anyway. Unless he is running 100 feet of tubing with an array of radiators along it, or some form of unconventional liquid cooling such as a bong or a series of TECs, its pointless.

Thanks Zero and Shadow

Zero: Thats what i was thinking, that it wouldnt make much of a difference on this loop, especialy with my setup (Res/pump, CPU, one 120mm rad)... Good to know it wouldnt be worth me unmounting everything and switching the tubes around on the rad (From out to in)

On a larger system with multiple blocks, I see Shadow's point and if/when i upgrade my loop, or find a case i like, AND will support a larger rad, i will definatly keep thoes ideas in mind and throw the rad on just after the res.
