cpu 74 deg gpu 40 is there something wrong?

[lexx320d]

during war zone my cpu is reaching 70 and my gpu is at 45

I have reseated all blocks and re applied paste
cpu is a i5 9600k 4.8
gpu is a and rx480
I am using a Phobya dc 12 260
Phanteks c350i cpu block
one alphacool st30 280 mm radiator


and a alphacool nexxos gpu block

any suggestions appreciated

thanks

A single 280 rad isn't exactly a lot of heat exchange for a CPU and GPU, but I'd still have expected better than 70c on the CPU.

FWIW, I have two 360 rads for an i9-9820X and GTX 2070 Super.

Was it ever any better than this or is this a new loop? What's the flow like, have you got a flowrate indicator/meter? What does the loop itself look like, can you get a pic up?

This is a brand new loop
I don’t have a flow rate meter currently installed
Flow seems ok it’s not super strong but it’s definitely moving I have a aqauamaster res being top fed so I can see the flow is there
I intend on improving loop but I want advice prior to either adding another rad or getting a stronger pump
If I’m only gonna knock temps down by 1-2 degrees I prob won’t bother
Any suggestions ?
Will post a pic shortly
thanks for reply

Whats the loop order? I'm going to guess, rad -> gpu -> cpu?[/

Your completely correct
I read and watched so many videos saying loop order doesn’t matter that I just took the easiest route
Do you think changing loop order will help with my high cpu temps?

Res >pump>GPU> cpu > rad then back to res

Order doesn't for the most part matter one jot, as the loop will reach equilibrium at some point anyway (the point at which all the coolant has heated to the point whereby the radiators can't remove any more heat, and that the CPU/GPU isn't adding any more heat - unless GPU/CPU load goes up). Increasing reservoir capacity makes the time taken to reach equilibrium longer, but won't change that temperature point.

Surface area of radiator, and airflow through them will make the most difference. With my loop, running a single 360 radiator will see my idle temps climb by around 10c, and my 100% load temps by more like 20c. As it stands (with the two radiators) I'm sitting around 35c CPU and 39c GPU when just doing basic desktop stuff, this rises to around 48c CPU and 58c GPU.

So do you think it’s worth adding another 280 rad?

Do you have any sort of estimate of how much another 280mm rad could lower my temps?

my current rad is mounted up too as exhaust

I would be placing second rad on front of case as Intake

thanks for your reply

I can’t find the exact max cooling capacity of the ST30 280.
Have a look at the Xtreme rigs review of the ST30.



It would seem that with around 300W to dissipate, my opinion would be that adding another 280mm radiator would certainly help, but you may only gain a few degrees. Just bear in mind that you still have over 20 degrees on the CPU, and your GPU looks comfortable.

If your temperatures are the maximum seen during a gaming session over several hours, then I would almost be tempted to leave it alone if you can handle the fan noise. Just bear in mind that the ST30 works best with medium speed fans, apparently.

thank you for taking your time to put the post and link together

ive tried it with fans and pump on full speed and my max cpu temp is 65 degrees I didn't see 70 once

the fans im using currently are the stock fans that come with the Phanteks evolve x rgb they claim to be radiator fans

I have a 240mm and 360mm rad (30mm thick) on my 9600k 4.8ghz 1.216v and rtx 2070 2025mhz 1.00v undervolted and I get 50c max gpu and 60c max cpu. Warzone is very cpu hungry if your not using vsync. I get 60-80% cpu usage and 60-80% gpu usage at 60fps. looking at around 54c cpu max and 45 gpu max while in warzone. do you have vsync on and what res you running?

it'll come down to how the cpu block is mounted and which oriantation you have picked, the 9th gen chips from intel use a slightly rectangle die which if you look at the motherboard and how the cpu is installed, the waterblock should be installed so the fittings sit in the horizontal position side by side that way you maximise the cooling of the waterblock your using.
Also because you have a 280mm rad only, you'll need to crank up the fans a bit under load to try and help the tempratures and a critical step is to have good clear intake airflow into the case too, this is often overlooked and thus problems start to happen.
If you want the best tempratures then it all comes down to radiator's the more you have the better the cooling and you can run near silent under load if you have enough radiator capacity, if not then you need to increase fan speed.

just noticed your cpu overclock, what vcore voltage are you running to keep 4.8ghz stable?

its just above 1.3

could you help me to get 4.8 stable at 1.2 ?

I followed this guide and used the dynamic vcore?
