Help with watercooling

kriiilllee · Nov 20, 2017

Hello! a little time ago o changed my build to custom waterloop to get my system lower temp, and in non stress mode, (just having pc on) i landed on about 33degrees C. yesterday and cleared out my waterloop cuz i changed my chassin and moved my rad and res. and now i have 40-42degrees on non stress. and some friends have around 25 in non stress and i wanna know if there is something i can do to get it lower and what i can do, if they can get lower temps i should be able to get lower aswell. below here is my pc spec and spec about waterloop.

Windows 10 Pro 64bit
cpu: Intel Core i7-7700K 4.2GHz Kaby Lake
RAM: 2x Corsair Vengeance RGB DDR4 3000MHz 16GB
Mobo: MSI Z270 Gaming M7, Socket-1151
GPU: 4095MB NVIDIA GeForce GTX 1070 (MSI)
Powersupply: Corsair RM 750x 80+ Gold

Waterloop:
EK-Supremacy EVO cpu block
EK CoolStream PE 240 (2x120)
EK-DDC 3.2 PWM Elite Edition
EK tank, EK-RES X3 150

If there is anything else you need to know let me know or if i forgott something

Thanks prehand!

sorry for bad pics and bad cable handling

The most likely culprit there is the spot you moved your rad to possibly being less cooling efficient, it could due to less optimal airflow through it, warmer air coming into it, or being in a more cramped space.

The problem is none of your pics show exactly where the rad was before moving it, or where it is now. All the pics are too close up, and leave out the most useful information. You could have at least explained such info, though pics would add useful details.

Lastly, provided you are well versed at draining, filling, and bleeding air from the water lines, it's likely rad placement. Air in the lines though can cause problems.

i moved the rad to the lower front of the case with 2 fans in front of the rad. https://imgur.com/a/t1MDZ there is a pic on the rad.
its not cramped there is alot of space around it.
i have drained, filled and done the bleeding and there is only small small bubbles in the system and some fog on the top of the res.

Small bubbles are not good. That one pic of your reservoir had me concerned about how well the bleeding was done. Also, where was the rad before moving it?

That last pic won't load for me btw, it just keeps hanging.

Okey thats not good obv, i did as internet told me, to fill it up turn pump on to push it out to the system and before res goes empty i stop and fill again and keep doing that until the fluid stays same level in res then i let the pump do the work and push it around the system for a while then i closed the res and did it again, next i shaked the case very easy and turned it back on. and let the system run over night for about 12h.
the foggy on the res they said was cuz i have warmer outside the res than the inside?
sry forgott the answer that before. the rad was placed on the top before, on the back above the mobo. like in the "ceiling" haha so the rad was in horizontal position before. and now its vertical.

As far as I know most tap the reservoir to coax excess bubbles out. Shaking the case probably isn't going to suffice to jar the trapped bubbles loose.

Do you have a flow meter installed btw? If you had one on before the change, you could monitor the flow before and after. Sometimes when a loop is drained and refilled bits of corrosion can get stuck in areas and affect the flow.

As far as rad position goes, the front should be better due to heat in the case rising to the top. This is of course provided the front of the case is not near anything, especially anything warm. Fan filters also affect air flow, so if the top of the case doesn't have them, but the front does, you have to factor that in.

Lastly, if the rad fans are speed adjustable, make sure they're running at the same speed they were before.

Hello sry for late reply, i been away for couple of days.
I read on the internets and i thought i did as they said and they said that it wasnt any big problem if there were some small small bubbles.
No i dont have a flowmeter or anything to measure flow or temp or anything except the temp meter on mobo and MSI program.
the front should be the best area for rads, and i have 2 fans going full speed into it.
Do you have any ideas or tips/trix i should test or change or anything? maybe how to get the last bubbles out of the system?

Nothing other than what I already said. I have to think if the manufacturer of the WC parts are telling you to shake the case instead of tap the parts most likely to collect bubbles, maybe they're worried customers will tap them too hard and break them.
