Are these normal temps?

[KhaderKh]

Hi,

 

I have 9700K OCed to 5.2ghz @1.35v and LLC 6 Cooled by NZXT X53 240mm.

 

On AIDA64 stress test the CPU draws 140w to 150w the temps hit low 80s.

 

Playing cyberpunk which utilize all 8cores the CPU draws up to 100w and temps hit low to mid 70s.

 

On idle temps sit a TT around 40c to 55c, fluctuates alot.

 

I know the temps are fine for the CPU but is it fine and expected for the cooler, is it under performing?

 

Pump speed is 2700RPM (Highest)

Fans speed is 1700 - 2000RPM (Highest)

 

Thanks

I'd say that's about right. My 9900k runs pretty toasty (as do all 9th gen Intel's) even with my custom loop. 5.2Ghz is pretty damned good though for a 9700k. I run mine at 5Ghz and get 100% stability but at 5.1Ghz I need to start using AVX offsets to keep things up and running. That being said, it only fails on Prime AVX workloads.

 

Maybe your idle temps are a little high though. When mine isn't doing anything it rarely goes above 30C but my livingroom is a cold room without the fire on.

 

Might be worth cleaning the IHS and block and reapplying some thermal paste.

Hi,

 

Today I built my 1st open loop water cooling for my 5.2ghz 9700K CPU.

 

I used EK-Classic Kit S360 D-RGB and added drain fittings to make it easier to drain and clean.

 

My loop is like this:

Out pump

In Rad

Out Rad

In Block

Out Block

In Pump

 

I have few questions:

 

1- What is the normal evaporation rate?

2- Are air bubbles normal? Does it affect coolong performance.

3- How often should should i drain and change the coolant?

4- can i upgrade later, eg. The reservoir, add GPU block...etc?

5- What is the life expectancy for the loop?

 

Any other advices?

 

Thanks

Nice build

1; It's not much, depends on loop temperature and ambient conditions, but would likely not be an issue at all, it'll get sorted when you perform loop maintainance and refill it

2; Yes, water has air disolved in it, and as it heats up and is forced through the loop air comes out of solution and forms little bubbles and air slowly bleeds from any area that has trapped air. It'll go away after a few days at most.

3; every 6 to 12 months usually is a good rule of thumb, depends on what coolant you used.

4; Yerp, that's the whole point of custom water cooling, you can do whatever you want really.

5; Unlike an AIO, custom parts tend to last a long time. Blocks can last over 10 years, some pumps do too. Rads can get dinged up in use but generally are the same. Fittings can also take a beating over their life and loose any plating on them, the tubes will likely go cloudy  eventually, so probably about 5 years realistically before you should think about giving it a thourough going over and replace anything that looks like it's not doing so well if anything is. You might get the odd failure here and there too. 

As for advice, not much, maybe when you do your loop maintainance you can add the GPU if they make a block, might need another rad though, a single, even good 360mm might get a bit warm with both of them in it but it might be fine, depends what 360 it is.

Thanks for the detailed answer, another question if I may, tubes are getting really hot due to heat coming from the GPU, is that normal? Can they handle that temps?

The tubes will get hot from the coolant being in them, but I don't think the GPU exhaust should be making get that hot. Is the pump running at full speed or reduced speed, is the radiator also hot or is it cool to the tough?

Pump is running at 70%, rad is fine to touch.

Can i know the loop temp?

You'll need an inline (in the loop) temperature sensor for that. How are CPU temps? seems like it's working normally, maybe when you perform maintainance give the tubes a bit more lenght and avoid the GPU area

Will do that, that for the advice. CPU temp is perfect for me max 70c, 9700K 5.2ghz 1.35v, 100watt draw on cyberpunk, both fans and pump at around 50%-70%

100 watts is pretty low power usage but the overclock isn't overtly heavy. Should be more than managable on a 360mm.

Yes inline temp sensors are a dime a dozen and are easy to install if you have an empty loop  

I have one that i installed on the bottom of my res because there is like 6 ports on it and i only use 2 so i just plugged one of those ports with a temp sensor, and it is right next to the outlet so it gives a pretty accurate temp of the fluid just before it enters my system.

Hi,

 

I recently bought and assembled my first open loop water cooling system using entry level EK Classic S360 kit, I know i shouldn't expect much.

The open loop is only cooling my CPU, the GPU is on air.

9700K @5.2ghz 1.35v, LLC lvl 6
Cache / Ring clock is 48

Temps on AIDA 64 is in mid to high 70s
Cyberpunk sits on mid 60s to early 70s
Other games at mid 60s.

GPU 6800xt, 1440p

Are these the expected temps?
