about Radiator Temps

post #1 of 5
Thread Starter 
This is the setup





The Top Half of the Rad is cold and the bottom is Hot.
is there something wrong? is it bad?is it supposed to be like this?
or should i release the air inside of it by unscrewing this and putting it back on again to release air?


im new to LC-ing.Need help on this thanks.

The flow pattern of a radiator is heat in on the inlet side, then it cools as it flows towards the opposite end, and then back again, so it's not abnormal for one quarter section (inlet quarter) to be warmer than the rest I imagine.

How are your temps on that GPU and/or CPU? If you're getting high temps and the radiator isn't seeming to be doing it's job, it may have air bubbles in it, which you can get rid of by leaving the case on its side and running it like that for a while so the air bubbles have an easier time exiting the loop.

Can we have other details on your loop, and any other symptoms of the radiator not working? It may be working fine if only the inlet side is hot and then it cools immediately, that sounds like great efficiency to me that it can get rid of all of the heat very quickly.

I will admit these pictures have me hooked and at the same time confused...Which side of the case is the rad on?

To me it looks like it is on the bottom of the case?

also are you running Slims on the inside and then regular x25s on the backside of the radiator?

Ideally you should match the speed CFM and Static pressure of the Fans for efficient cooling.

Added: Your rad is so close to your case that I have to assume you are seriously restricting airflow.

If the top is cold and the bottom hot that would indicate that there is no water in the top. I'm assuming that you have it mounted with the barbs at the bottom, in which case a large bubble will form at the top of the rad, as the tubes form an inverted "U" shape:



In your case the water is not making it all the way to the top of the rad, so it can't displace the air. This normally happens, but needs fixing. You need to get the air out of the top of the rad, either by unscrewing that bleed screw or by tilting the rad so that the air can escape.

If you unscrew the bleed screw, make sure that your res is full and your pump running, loosen the screw and allow the air to escape but be ready to do it up again as soon as water starts to come out. Leave everything for a bit and try again until there is no more air.

-sorry for bad angled pics.
-The RAD is at the Back of Silverstone RAVEN RV01
-3 Yate Loons 140x140x25 mm 1500RPM (Back of Rad/Case)-Push
-3 Yate Loons 120x120x20 1800RPM-/+ (Front of Rad/back of case)-Pull
Air in->140mm Fans->Rad->120mm Fans->Back of Case->Air out
