Isn;t that noisy ? having all the fans on top of your head?
I had 3 bottom fans on the Silverstone Raven 2, with rad on top of them. When i started having High temp problems, I added one fan over ( following same wind direction - going up) and it solved the high temp issue.

Now i added more water blocks and had to move the party outside the Raven2.

I am thinking about doing the same with the rad, I have a HX-CU1020V with 3 Xtraflo Coolermaster fans. I am also wondering if connecting 3 more fans on the other side will help to low down temps.

Depending on your fans putting some on each side, all fans pushing or all fans pulling may work better.

My suggestion is to try all three configurations and see which provides the lowest temps.

I had chosen some ultra quiet fans so even on their highest setting I don't really hear them. Of course I have a 9 year old computer running nearly 24/7 which is pretty noisy.

From the issues i've dealt with and finally seem to be grasping several things come into play:
1. Fin density of the Radiator. I have 2 Koolance 30fpi Rads, a 1x120 and a 3x120.
Easy answer to this is: If you can count more than 20 fins in one inch, you need a fan that turns around 1600 rpm (2000+ for the 30 fpi) and produces alot of static pressure.
2. A GOOD FAN! One that produces at least 5.0mm-H2O of static pressure. This is the push needed to get the air through a radiator with mid to dense fpi.
I have/had 6 Scythe fans, 3- 1900rpm slimstreams, and 3 3000rpm ultra kaze's. loud, expensive, and created a total static pressure roughly around 21.0mm-H2O. 6 koolance fans, 30.0mm-H2O. win.
Easy anser to this is: Buy these Koolance fans:http://koolance.com/fan-120x25mm-108cfm
I did, my Koolance 3x120mm 30fpi rad stays at room temp at idle, coolant temps rise only 2 to 4 degrees Celcius in a room temp of 31-33C (87-91F).
3. Flow. Its Key, Make sure you are cooling all parts of the system, not just the blocks, i'm reffering to pumps, I have my rad before my pumps then to cpu-1x120-mobo-gpu1-gpu2-3x120-dual pumps. When I had only one pump in the system, it would not move fluid with enough speed to clear air pockets and cool the system effectively. So make sure you aren't running any bends or overdoing your pump. Right angles on tubes are bad, straight good. less flow restriction.

4. Good luck. sorry for ranting. The last 3 years i've been reading and plotting a crazy system build with koolance parts and so far it has paid off in spades.

you'll still need a fan to move air inside the xbox. not sure i could see one. but you should. everything else in there needs to breath

Yup moving air inside the xbox360 is important which is why I left the original fan connected. It just runs at its lowest speed now :mrgreen:

Also for those with an xbox360 or xbox360 slim all chips except the small voltage regulators should have a heatsink on them if at all possible. For the regular 360 version with HDMI out that will require six of those stick on heatsinks. Four small ones for the RAM chips and two large ones for the Hana and the other chip.

Amazon.com has a heatsink kit for the 360 for sale.

I did see a waterblock for the 360 that cools the RAM as well, but it was at least $100. I am seriously considering getting an XSPC Xbox 360 CPU/GPU waterblock. Good thing about it is I will then not have any tubing running under the DVD drive. Will require a couple 90 degree nozzels though. How well would that waterblock work? Looks like it might have a little better flow than the Koolance blocks I currently use and would also stay in contact with the CPU and GPU better.

I also just realized you are sucking in all the heat off your monitors and recording gear. You want the coolest possible air reaching your rads.

And yes that little gap can effect cooling as the rads pick up dust the airflow will find the least restrictive path to move through. There are various products on the web the can be used. cheapest and quickest means: electrical tape and or gorilla tape.

I agree about the heat from the monitor.

At room temperature my 360 runs between 82F and 86F so I am happy.

For that small gap if I can find some thin black rope caulk or some speaker sealing material (similar or the same as the rope caulk) I may use that.
