Hailea HC-500 or HC-1000 Any Good For Water Chilling?

[dr_dx]

I also have a Hailea HC-500 but the temps of the cpu isn't that good, but temps of my 2x5850 are good.

[Hardware]
Xeon W3540
Asus Rampage II Extreme
Corsair Dominator 3gb 1866 cl9
2x HD 5850 ,1x EK-fullcoverblok and 1x MCW60-r + Swiftech heatsinks

Hailea>Hydor l30>cpu (XSPC X20 Delta V3)>5850>5850>reservoir

temps


Ambienttemp=22degrees
Humidity=51%
Hailea set temp=14degrees

setup

The ddc 1 pump+ reservoir i did't use.

So what could be the problem ,why the temps of the cpu is so much higher?

A couple of things:

1. You have suction head which is a big no-no. You will cavitate your impeller and ruin it. Your Hydor L30 intake needs to be level/lower than the output of the chiller if you have it between the chiller and the cpu block. If you relocate it to the input side of the chiller, then it needs to be below the water level of the reservoir. This will also give you better thermal performance because the chilled water goes directly to the cpu and doesn't get heated up by the pump.

2. The Hydor L30 is only rated for 75" of head. Most sites that sell chillers say you get at least 6' (72") of head loss going through a chiller. That leaves you with 3" and you can be sure with all of the vertical elevation, bends, water blocks, tees, etc. you have WAY more than 3" of head.

You have a closed loop system which skews the head loss issue ( you still have a LOT of friction loss), but I would at least put the Hydor down below the output of the Hailea and see if that makes a difference. If not then I would change it out for a couple DDC 3.25's in parr. on the input side of the Hailea.

Also, Hailea recommends 317g/h minimum flow rate for the 500. The Hydor L30 will barely do that at 0 head; you can bet you aren't getting minimum flow rate through it with that pump.

Just my .02
