Needing some advice for first liquid cooling purchase - Page 2

post #11 of 14
Hello! Welcome, fellow Nick cheers.gif
First, allow me to say: Yes, believe the hype boxing3.gif Watercooling is awesome!

My GPU under load dropped by about 25 to 30 C, with about 18 C dropped on the processor with a heavy OC. The Edge kit you have selected seems to be a good choice, the Apogee HD is a top performer, but you will want at least a 320 radiator if you want to cool a GPU as well as CPU. If you just choose one for now, that kit will let you upgrade later thumb.gif

As far as temps, you should be seeing substantial temp improvements going from air to a good liquid cooling setup. Exactly how much of a difference depends on your old coolers, your new cooler, and your ambient temps. In your case, you already have fairly good air coolers, so it wont be as big of an improvement as if you were using stock reference cooling on your gpu's for example, but it will still help.
To give you an example, my refrence GTX 280 ran 40+ degrees higher than my liquid cooled 295 at all times, even though the 295 is a significantly hotter card.

So these chillers are only necessary for those extreme overclocker's wanting to break records and things? Kinda like how they use liquid nitrogen and stuff.. And that is great to hear, I do have quite hot ambient temps because I live in Australia (25-40C) So that is probably my main problem with my temps. Do you think by cooling my CPU down it might possibly lower the temps of my GPU's? I have noticed from having 2 multi-GPU configurations (HD5850 CFX and GTX 580 SLI) that the card that is closest to the CPU ALWAYS gets hotter than the bottom card. When my top card is sweating it out on 95+C my bottom card is usually happily running on 70ishC. So, do you think that by cooling my CPU down a bit (Say I got it down to 60C) that would cool my top card down?

Also the heat from the lower card rises to the upper card causing higher temps. At idle my 2600k @ 4.8 is at 17C and load with Prime it's no higher then 51C. My GPU's are sitting at 27c idle and 40 full load on Furmark. The best part of it all for me is I can barely hear my rig at all.

What this means is that the hot air from your cpu can be blowing right into your gpu, effectively heating the gpu. This is actually true for all components in your case, not just the CPU and GPU, and it is not unidirectional.
When you liquid cool, you have the option of placing the radiator someone where on the perimeter of the case, or even externally. This effectively means that almost all of the heat of the liquid cooled components can be released into the air OUTSIDE the case as opposed to inside it. This keeps the ambient air temp within your case cooler and almost entirely removes the issue of one component substantially heating another component.
So short answer: by liquid cooling your cpu, it will also help your gpu, and vice versa, even if the second component is still air cooled.

Thank-You very much, you have answered all my questions well and helped me a lot! Rep+1 for you sir!

Sounds fantastic! Thanks for great reply, I am very happy to hear that I can finally get rid of that stupidly MASSIVE air cooler lol.. Thank-You
