D5 Pump PWM connection

post #1 of 8
Thread Starter 
Ok, I got my EK water cooling system up and running. My idle temps on my 5930K intel processor is just under 30 C. I ran prime 95 for about 20 minutes and my temps got into the 60 degree range.

I was expecting lower temps. I noticed that the fans did not ramp up during the test, at least not to full capacity. Also, I did not see the pump kick up to full speed.

Currently I have the PWM from the pump connected to the CPU Fan header. I have done some research on line and from what I understand, I should hook the PWM to a chassis fan header and run the pump at 100% capacity all the time.

Should I run the pump at 100% all the time, or just let PWM control the flow?

Also, the thermal paste I used mentioned a break in period for the thermal compound. Should I give the thermal paste time to break in and re-evaluate?

From what I've read, prime95 is not recommended anymore and can actually damage your cpu. I haven't really looked into it in a while so maybe someone else can chime in here too. I've started using Aida64 for testing and I like it.

Ok....well we know you have an EK D5 pump....at least we can assume that. No clue what else is in the loop, so it's kind of hard to help or make suggestions. Though, running a D5 at full speed is very, very rarely the best idea. For example, most people run a Vario at 3-4 (or ~3000 rpm), I have a PWM and get the best temps with a two block+two rad setup at ~2800rpm max, and have low loads at 1700rpm for silence.

I'm not sure why you thought a 5930K running P95 should be lower than 60C, but that is a very good temp for that. For a more realistic representation of your cooling, you should be running AIDA64 as already mentioned, OCCT, IBT, x264 or the like. P95 is not a representation of real world full load in any way.

And what TIM are you using that says it requires curing???? I haven't seen that since the stone age when people were still using Arctic Silver.

Lol......yes, it is arctic silver, you called that right.

The parts list is as follows:

EK-XRES 140 Revo D5 PWM System- the setup included the pump, reservoir, 240 mm radiator, and water block.

Promochill 3/8" inner diameter flex tubing.

Corsair High Pressure Fans for the radiator.

Motherboard is the Sabertooth X99

Right now, all I am cooling is the CPU. My concern is that I may not have applied the TIM correctly or Im not using the right connection for the PWM pump.

Thanks and any in site would be appreciated.

Sounds like you did everything right. Well....except for using Arctic Silver instead of the GC Extreme that comes with the kit. Change out the TIM and all should be good. A small loop will likely never need the D5 at more than 2000rpm.

I have a 5930k as well. 60* is about right for a temp when running p95.

Thanks for your help and advice!!!!!!!!!

Do you see any reason to move the PWM pump connection away from the CPU fan connection on the MoBo.

Also, should I set a minimum pump speed?

It is fine on the CPU fan header. It doesn't really matter. I have put my pumps in both places, and as long as both are PWM, it is the same.
