Also, i do not have any means to measure either temperature of the coolant, nor the flow rate. All i know is that it does flow rather slowly, but i have 0 experience with watercooling, so i have no idea how it compares.

You can find more pictures here. There are a couple of when i finished mounting the EK waterblock, then there are a couple of the 2 titans and finally some of the whole build. http://imgur.com/a/4XeD5

Maybe the loop is too restrictive for the pump? It first pumps to the front rad which is set up horizontally, then to the 2 titans, then into the upper rad, from there on it goes to the cpu only to finish back to the pump.

Thanks again Gabriel, i really appreciate your help.

You welcome mate, we will figure this out. A d5 at setting 5 should be plenty and it is a very good pump. The flow should be good too and not slow as you mentioned. So right now I am thinking maybe the in and out of the cpu block are inverted. Did you by any chance disassemble the cpu block? Are you cpu block marked with a In and out? Are you sure the flow path is in the correct orientation? The same goes for the pump top. Most tops have a in and out marked and if you switch those that might explain your temps if flow is hampered somewhat...Also I would suggest to take this to this thread where a lot of experienced users in water cooling camp...

Had some time while my kid and wife took a nap today, so I pulled my cards apart and put IC diamond on them. Idles dropped a couple degrees and peak loads on FSX and FSU are under 70. Typically around 68. Not to shabby for a ten min fix. And it takes a little longer to hit that peak. Going to heat soak in heaven for a bit and see how they do.

lol - true! Heaven 4.0 heats up the whole pcb!

I just checked if the tubes are attached correctly to the CPU block and sadly they are. At least i think. There are 2 arrows, 1 on each port. One is facing away from one port (i suppose this is outlet) the other is facing towards the other port (must be the inlet). The tubing on the pump is also correct. I have a Pump+Reservoir combo from EK, and i configured it exactly like they say on their manual (Step 5): http://www.ekwb.com/shop/EK-IM/EK-IM-3831109842652.pdf

So yeah, seems something fishy is going on.

Is 80°-85° C normal for a water cooled CPU at least? It's a 5820k overclocked to 4.3 Ghz (voltage to 1.35).

Also, i will ask the guys in the thread you sent me, maybe they know what's up.

Thanks a bunch and have a nice evening Gabriel.

You can back down that core voltage on the cpu to around 1.27-1.30 and be stable most likely. 80-85 is too much mate. Something odd in this loop... I started to wonder is there is a blockage somewhere in the loop....Take to the wc thread and let's continue there with the help of the others there.

edit - also, a full component list of the loop will be helpful. cpu block, type of fittings, pump, rads, tube and liquid. When you post there put those info too.

If its an EK block and you took it apart you might double check the orientation of the jet plate inside, I can't tell you how I know but if the jet is off by 90 degrees you'll get pretty high temps on the cpu rolleyes.gif

So, after some Heaven, capped out at 70 degrees. Made a more agressive fan profile, 65 is as hot as they get. Still wont clock any higher though. lol

Hi there,

Few things it could be :

1.) Flow rate relating to GPUs : from what i can see you have your gpus in parallel, if you have a low flow rate then this could seriously affect temperature of GPUs.

EG gpus in parallel = slightly better than 1/2 flow rate through each GPU vs series , slightly more than 1/2 pressure . If you have say 150 l/hr flow .. eg low flow rate for system then GPUs would be around 75 l/hr = a low flow rate for a gpu that would affect temps.

You might be better to put GPUs in serial with low flow rates , if the above were true and you are around say 150 l/hr now in parrallel then flow could drop to around 130 l/hr for system once gpus are in series (extra resistance) but the gpus each would have 130 l/hr vs 75 l/hr flow if you get my train of thought.

Without a flowmeter its guessing at what your flow is but certainly parallel requires a certain amount of flow rate to be effective due to it splitting flow evenly.

2.) Flow rate relating to Pump : Other thoughts if limited on time and have a few $ spare , try a stronger pump .. you could remount everything and have the same problem if flow is the problem. If you don't have a lot of time buy a PMP500 (strongest of the 12vdc pumps) and hook it up to the loop , the D5 is ok .. but not particularly strong pump.

3.) Liquid Temp : You need a liquid temp sensor somewhere , i was just thinking then if your liquid is in the 50c range no amount of flow will help . If you liquid temp is high then it points to insufficient radiator / fan cooling ability.

4.) Mounting , never did a terribly bad GPU mount to be honest - certainly not one that would cause the high temps you are talking about. My method is to apply thermal grease to both surfaces spread even and thin with a razor blade or plastic blade - there's no guess work then about have you covered the gpu. PK1 Nano is the best TIM i've used. The star method you used likely used 5x more grease than you needed too - but i doubt its caused +20c temp delta your reporting unless you gpus screws have some slack left (they should be firmly screwed in).

Out of the above 1 and 4 won't cost you anything but time. I'd recommend you get the liquid temp sensor and a flow rate meter also as you can pinpoint where issues are if they develop over time.

If you're talking about the CPU block, it's a Phobya one. UC-2 copper, if i recall correctly. I didn't take it apart anyways, i installed it exactly how i took it out of the packaging. I must've ****ed up somewhere, that's for certain.

This is brilliant advice, thank you for taking time to write all of this.

It seems like i won't get around the fact that i will have to drain my loop. This being my first loop and all, i didn't really plan things out correctly, so i have no drain pipe/tube or any system for that matter.

Unless i can install the flowmeter and temp sensor without draining my loop?
