Introducing the LAMPTRON CW611 water cooling assisted fan controller! - Page 35

The CW611 is about as good as you will find anywhere near that price range . . . .

If you want to be able to create custom curves and have nearly infinite software capabilities, you have to make that quantum leap to the Aquaero 6 with its Aquasuite software.

Expensive, but then you didn't skimp any on the rest of your system, so not really so over the top.

Thanks Darlene... It really is a bargain for how well it works. Wondering if I should move my temp sensor location to the inlet of the first rad? It would be the hottest part of the loop and should raise my coolant temp enough to perhaps allow a little more flexibility. I do like the flexibility of the Aquaero but don't like how everything is priced individually - even just to get a black trim plate for the screen is extra. Making silver the default had to be a monetary decision as black cases probably outsell silver by at least 4-5:1.

First the system...
4790K CPU with XSPC WB
2 x GTX780 GPU's with XSPC WB's
ROG Maximus VII Hero MB
Caselabs SM8 Merlin case
Coolgate 360mm x 60mm rad 7FPI x 6 GT AP13 fans in push/pull in front of case
Coolgate 480mm x 60mm rad 7FPI x 4 GT AP13 fans in push in top of case
Swiftech D5 Vario pump with EK X-top
Flow starts at the bottom and works it's way up through CPU, both GPU's and then top rad and front rad.
I have the top rad fans connected to channel 1 on the CW611 and the front rad fans on channel 2. Both channels get coolant temp from inline temp sensors at the out port of the front rad. This should be the coolest point in the loop as coolant has passed through both rads at that point.

I have both sets of rad fans set to 24% min and 100% max with target of 25. This gives me a nearly silent system at idle and 24% is the minimum reliable start up voltage for the AP13 from what I see. My problem is that the fan speeds increase very slowly. For example, I'm doing OC validation on my 4790K and my fans will max out around 56% at 100% load in AIDA64 stability test. Coolant to air delta is about 6 deg C and coolant temp maxes out around 29 deg C with room temp about 23 deg C. This is giving me higher CPU temps than I think I should have with such a beefy loop. The only way I can see to get the fan speeds higher under this load would be to have a higher minimum speed which would defeat my plan for near silence at idle. I wish there was a setting for target temp lower than 25. Of course when I stress the GPU's then temp rises faster with faster fan spin up but I still never reach 100% on the fans. Am I missing anything here? Thanks
Use speedfan and define your own curve. I'd also plug a temp probe to your motherboard, measuring water temp. Then you could adjust fan speed according to coolant temp.

The problem with your CPU probably lies in the IHS: it's not soldered. That's why people get so high temps with such low power CPUs frown.gif I'm in that boat too

Besides that, I think that your rads are too thick for such slow fans.

Thanks. A few things...

Speedfan does not support the Maximus VII Hero currently. I currently do have temp probes in my coolant and the CW611 is controlling the fans on the rads based on the coolant temp. I do think the CPU temps are probably higher due to the IHS even with the improved TIM used on Devils Canyon. My last CPU was a 3770K which I delidded and there was a significant improvement. Not to the point where I want to delid this one just yet. After a year I will consider it. I do think higher RPM fans may give some improvement although Skinneelabs tested these rads when they were new and found 1200RPM was about the most efficient due to them having such a low FPI of 7.

Edit: I see thew latest version now does support the Super IO chip on the Hero. Thanks for the advice. I will check it out!

Devil's canyon's TIM actually remains the same redface.gif
