Well I have the Freezone Elite but have not modded it at all.
I used to run a full water cooling loop and did so for over a year.
What appealed to me with the Freezone is how lazy you can be with it. I was spending so much time maintaining my WC setup I was not enjoying overclocking or using the PC.
So far the Elite has been great. I run it at 65% as its a good sound/temp compromise.

Depending on ambient my CPU sits at about 30 - 35 Idle and then will heat up by about 6 - 8c when under full load. I still need to get a new motherboard before I know my temps accurately as the core sensors are not being read correctly by my Crosshair.

I look forward to the TEC discussion here

Will your CPU be a bottleneck?

The tube you ordered does not fit over the blue tec blocks. I had those tubes too, but I had to order the 8mm ID tubes.
The Shutoff nozzle sounds like a great idea

@laurie: I hope you get urself a nice board soon, so you can c what the real temps are for the 940. adding a 240rad to the loop would sure drop ur load temps.

1/4" ID is 6mm and 3/8" ID is 10mm.
8mm would be 5/16", I'm not sure where I can find that.
The norprene tubing that CoolIT uses and sells is 1/4" ID 3/8" OD.
It probably needs to be stretched in hot water first. I had no problems with Bitspower 1/4" ID barbs for the CPU block.

You can always try, but there was no way I could fit them...not even with hot water. Note that those Neoprene hoses are way more flexible than the pvc tubes and they expand more.
Just trying to prevent you to buy the wrong tubes like I did....

Thanks, I appreciate the warning. I'll be using the stock Norprene tubing to connect the blue TEC blocks. I'll put the pump and res outside the case so the PVC tubing will be only connected to those parts and the ones inside the case.

I finally received my D5 pump top and Norprene tubing.

I did some pressure testing on the CoolIT pump and D5 with a flow meter. I connected the pump directly on the PSU so it would get maximum power.

CoolIT pump alone < D5@1
CoolIT pump alone = D5@3 + GPU
CoolIT pump alone = D5@5 + CPU + NB/SB + MOSFETs
CoolIT pump + Coolit CPU = D5@3.5 + CPU + NB/SB + MOSFETs
CoolIT pump + CPU = Drip-drip-trickle-trickle

The CoolIT pump alone has less flow than a D5 at minimum speed.
The CoolIT pump alone has about the same flow as a D5 at speed 3 with GPU block installed.
The CoolIT pump alone has about the same flow as a D5 at speed 11 with CPU, NB/SB and MOSFETs installed.

The CoolIT CPU block is a LOT LESS restrictive than the aftermarket ones I tried. There was barely any water moving with the Enzotech Luna, lower flow than that and the water would stand still.

Still no ideas about flow speed vs temps but the results should be coming in a few days. Whatever they are, I'll probably end up chucking the CoolIT pumps anyway.

If high flow is better than low flow, I'll be changing the D5 for a DDC3.2 w/ XSPC res top as the D5 is maxed out anyway but if low flow is better, the D5 with a very restrictive loop can be matched to provide the same speed as the CoolIT pump or even lower.

Low flow is never better it never has been and never will be (thats if your excluding any additional heat dumped by the pump to make it move faster)


Here's a link to some testing i did

I tend more and more to trust the experienced OCN TEC guys over CoolIT's ramblings.

I'm leak testing right now but I'm sure my experimental results will point the same way as yours. I'm almost tempted to reproduce your setup with two pumps.

It's surprising that I had any flow left using the original pump and a restrictive block. Adding the NB/SB and MOSFETs would have probably killed whatever little flow was left.

I sure am curious to c the results using a restricted block and a highflow pump. If highflow has better performance, then I'll be getting a new pump and block

yeah well they have a vested interest, so it's hard to take what any salesman says at gospel
