Add Rad or Swap Rad

demonstag · 8 Dec 2011 at 18:00

Hi All,

I currently have a 240Rad cooling a 2700K & ATI 6950(flashed to 6970) I know I need a larger Rad. I am curious to find out if I would be better swapping the 240 for a 360 or adding the 360 to the loop and keeping the 240 in situ? Will I see much cooling difference between the 2 options? :confused:

Keep the 240 and add the 360 as well, that will give you the best temps.

Have a look on, i think it is, skinnee's website. Has a calculator.

I think you'll find that you're not limited by radiator dissipation but more heat transfer. Do the rads/pipes get hot?

But if you've space for the rad why wouldn't you.

Adding the 360 rad will increase your thermal maximum, and hence thermal performance. I say add rad =] As for noticable differences, you should notice a few degrees difference from normal use, but if you're running IBT and some sort of graphics test at the same time the load differences should be considerable.

Being a very big Noob when it comes to Watercooling I greatly appreciate all the advice given, so thanks to all.

Since adding the Full gpu block to the loop I have noticed a large increase in temps idle now is approx 30°-34°C but that is the 2700k O/C @ 5ghz 1.4v(27°-31°idle)(55°-61°Full Load) & Powercolor HD6950 @ 940 + 1420(30°Idle)(34.5°Full Load).

I had planned to swap the 240 with the 360 in the roof of the HAF X case and place the 240 outside at the rear as there is no room in the case as the pictures show in my other thread:

I have also been looking at adding a kill coil and Mayhems Aurora Blue. question is do I need the kill coil with this coolant? I currently use the standard EK coolant that came with the EK HF240 Kit without the kill coil as I was aware that this coolant has inbuilt biocide, I think :confused:

Any further thoughts or suggestions welcome

Cheers :cool:

No need for a kill coil with that:

Mayhems Pastel Fluids has biocides and inhibitors included in the mixture.

TBH i'd swap to the 360, see if your temps on the cpu actually go up much.

If not then you can sell the 240 and make a bit of money back.

Your load temps look great, don't worry about the idle. You just have a high T delta. If you switch rads this will lower, and theoretically the load temps will lower too, but by how much exactly I'm not sure.

This is probably a real noob question but here goes, What is a high T delta? :confused:
