Need help Custom Loop

aida64 hit 80 within a few minutes while h115i never excess 75c.

So sad, thought custom loop can give me 10C different for the cpu compared to h115i platinum.

That's definitely curious. With your 280/360 rads, temps should be at least the same or better as with the H115i Platinum. Did you try to spin up your radiator fans? Or are they already working at higher speed?
Check the CPU waterblock inlet and outlet port. Are they connected as it should be?
 
Rev all fans up to 1200rpm and the temp is cooler but there is still some spike to the 80s.
 
Mounting pressure on the cpu probably isn't high enough. I've had it too low a few times because I've been worried about damaging the board.

Mounting pressure makes a huge difference.

Also ensure you have the inlet port taking water in and not pushing it out.
 
I dont like the mounting mechanism of this block. Thats why I order a different one and see of anything good happens.

Yes low mounting pressure or inlet outlet interchanged could be two reasons. The temps should be definitely better than with the AiO. Or still too much air in the system
 
whats the pump speed plz?
 
I have a customloop cpu/gpu 2700x/1080 and with aida64 stressing everything apart from HDs for a hour I get 62c on the cpu and 50c on the gpu. your temps are ok bro.

He has spikes over 80 and worse cpu temps than with the AiO. That shouldn‘t be especially with a 280/360 radiator combo. The AiO has only one 280 rad.

the spike could be from a single core hitting the max, I have my 2700xrig on a 4.2 all core overclock theres no spiking but on my other rig a single loop 7700k it has spikes .
 
This is weird guys. Temp is still high. I used to have this temp at 5.2ghz 1.36v in bios. Now its at 5.1ghz and can't even pass linkpack due to high temp; it passed before. something wrong with my set up?

Funny thing is I bought corsair xc7 block and the temp is even worse, then bought optimous v2 block and the temp is not much better than EK velocity, so I decided to turn the block 90 degree and the temp is as good as the h115i platinum or a few degree cooler.
 
Perhaps there were little air bubbles in the waterblock and with the new arrangement air could better dissipate.
 
thats why i asked what pump speed ya have because there are more flow restricted blocks then others.
maybe it runs on 300rpm?
and ya now have a gpu+cpu in the loop instead of one 280 only for cpu. more radiators dont help at some point if they are inside the case.
but thats just my opinion.

Anyone know how to make water inside the loop cooler without a chiller? When I cold boot the pc, water temp is around 22c then it heats up to 26c-27c. When I stress the pc, water temp goes above 30c. What can we do to make water temp around 20c.

If you want to go sub ambient you will need a chiller. If you want only better water temps, but not sub ambient temps, then simply speed on your radiator fans ;). But if you are at 22 degrees ambient you won't get water temp to 20 degrees without a chiller.

Or put some ice cubes in your reservoir :D

For 1.35v that seems pretty normal. If you want better temps I would try to run the system at 5ghz with lower voltage the difference in performance is going to be negligible in everything except benchmarks and heat.

Every chip is going to perform a little different due to variances in the ihs so I wouldn't try to compare your chip to others with completely different setups. That being said mine chip hits around 90-91c 5ghz 1.28v after about an hour in blender your cooling is better than mine so your's should be a bit lower.

My bad should have read further back...... That is super odd that the corsair h115 is outperforming your open loop you should be around 5-7c lower assuming identical ambient

I thought he fixed this issue by turning the water block at 90 degrees. His open loop has also to cool his big fat video card :D , so temps aren't that bad at all. I have only a 6-core cpu running at 5 GHz and a RTX 2080 and water temp at idle is now also at 26-27 degrees. Ambient at about 21 degrees.

Interesting, if my h150i didn't perform well at 5ghz I planned on doing an open loop luckily for the majority of task I use it for its fine.... My 5820k ran pretty hot under AVX loads at 4.5ghz as well

It has a 360 radiator only for cpu cooling, that's pretty sufficient I would say. The advantages of an open loop is to cool your GPU and here you get really good temps compared to air cooling. And better boost clocks also ;). When I benchmark cpu with OCCT AVX512 and small dataset, the limiting factor is my vrm...my cpu stays at about 70-77 degrees but after 10 minutes benchmarking my vrm begins to throttle. It's only in this case a limiting factor, if I don't use small data set then it won't throttle.

My GPU stays at max at 50-52 degrees in games. Won't reach higher temps in gaming and also in benchmarks like 3D mark firestrike it won't go higher.
 
My custom loop make my cpu is 5c-7c cooler than h115i platinum plus my gpu is never above 50c during gaming.

That‘s the really nice thing here. Best boost clocks with your 2080Ti at these temps.

Edit:
Did you already overclock your GPU?

You're golden then those a pretty good results afaik.... I'm jealous my strix hits 68/69c heavily overclocked though.
