Lowering temps on CoolIT Vantage

[Gundog48]

I've set up my CoolIT Vantage and am pretty pleased with it, although I would like to make it slightly cooler. When gaming, I am getting water temps of 37*C which I would like to lower as I am planning on a 4GHz OC with my 1055T, it's currently on stock after I reset the CMOS.

At the moment, I am using the stock fan with it set up as an exhaust at the rear. Silence is a big thing for me, so if I upgrade the fan, I would like it no louder, and quieter if possible, than the stock fan. I have thought about setting the rad up to intake cool air from the rear or top. At the moment, I have an 1x 120mm intake, 1x 220mm side intake, 1x120mm rear exhaust (rad mounted here) and 2x 120mm top exhaust.

How would you recommend repositioning the rad and what quiet fan would you recommend?

iv just setup an eco on a friends system which is a similar setup.
running it as they recommend as blowing out of the case an i7 d0 @4.0ghz (1.350v) maxxed at 81deg with 10 runs of IBT on very high. i switched the fan around so it sucked into the case and it dropped full load temps to 71. extremely impressive for just a config change.

i think as long as you have a few fans in the system ablwe to move the heat then that is by far the optimum config unless you have it push pull which should drop it 1-2 deg further

if have it blowing in on the rear 120mm fan hole, that way the heat just gets whisked out up into the top vents, and as for fans with it having ~20fpi on the rad your going to need a fairly quick fan to get the cooling performance so it will never be silent on full load. I wouldnt like to recommend which fans as i havent tested with many yet on high fpi rads, in progess now with a 30fpi rad lol.

You'll need to compromise cooling if you want a quiet solution. Perhaps you could switch the fans to the Akasa Apache which give good results.

The Apaches were something I was considering. Installed one on my friends computer and that was extremely quiet unless maxed out. As I said, I'm pretty happy with the volume of the stock fan, would just like a fan that can cool better without going louder. Am I looking for a high static pressure then? I don't want to go push pull as it sticks out too much for my liking.

High static pressure is desireable when you need the air to push through a restriction, such as a radiator or heastink fin array. A fan with low static pressure but high cfm would just have it's air buffet against the fins and not actually be pushed through and a lot of that airflow will be wasted. The Apaches are by all account good static pressure fans like the Noctua and a few others, which are great on heatsinks.

I'm sure I read a fan comparison once where they actually measured the air penetration through a heatsink and compared a good high static pressure fan against a standard case fan of similar cfm and the difference was quite palpable. I didn't save the link though.

Thanks for the info then. So when I finish my HAF 932 mod I will put the rad on the rear fan slot as an intake in push configuration. Considering cutting a fan hole in the side panel to have it intake from the side but I think that would look bad!

Oh, and I keep getting this gurgling sound like water being squeezed through a hole, I think it may be some trapped air in the loop. Is this normal on these systems? Personally I would have preferred a quality air cooler, but as a competition prize I am not complaining!
