top radiator is cooling a lot more than others... ?

post #1 of 4
Thread Starter 
this is my loop

res
top 240
front 2x120
bottom 240
back 120
pump and blocks (cpu + gpu)

all with the same fans at the same speed pulling out, yet the top rad puts off noticeably more heat than the rest. i know part of it is just because its first in line but it really feels like its the only one doing work. also i just added 3x120 worth of rads and noticed little to no temperature improvement so im wondering what the problem is. i hope you can give me some insight here. thanks

The laws of diminishing returns shows it's head very quickly in water loops. For what you are doing, it is entirely possible that a dual 240s are all you need. What were your temperature differences before and after the changes? Have any temp probes in the water itself? There was likely a 2-3c water temp difference when adding the additional radiators, but only a faction of that will apply to the actual CPU temp.

The basic rule of thumb is single 120 per device cooled. I prefer an additional 120 as a buffer. In your case, it looks like you have the CPU and 2 gpu's to cool? So that goes right in line with what I prefer, 480mm total for your setup. thumb.gif

i am a firm believer that 99.999999% of people us way more radiator than they need. i am going to agree with butcher here.

well that's disappointing. so I guess I'm limited by the heat conduction through the blocks now
