How high does your liquid temps go?

system:
5820k @ 4.4GHz
1080ti 2050/5800
Waterblocks over CPU, motherboard VRMs, GPU core and GPU VRMs
radiator space, 600 x 400 x 30mm with two 200mm fans running between 5v and 9v (water temperature dependant)

idle: water temp ~1.5C over air temp
encoding: water temp ~2.5C over air temp
gaming: water temp ~4C over air temp

Depends if the side panel is on or off the case lol!

Under Load:
Ambient: 20 degrees
In case temperature: +3 degrees typically
Liquid Temperature: + 6 degrees over incase temperature typically

So in the above scenario Liquid temp would be 29 degrees if room temp was 20 degrees. GPU loads around 35 degrees, CPU in the 50s

I actually saw no difference at all whether the side panel was on or off, so left it on to keep the noise down as tempered glass has decent noise dampening properties.
 
9700K @ 5.2 all cores
1070ti
XSPC RX480, RX360 & TX480
Bykski block on GPU
Corsair XC7 CPU block
Alphacool Eisball with D5 pump
All Corsair ML fans running at constant 750RPM

Ambient water temp: 27c
Gaming water temp: 34c
Aida 64 GPU & CPU stress test water temp: 41c

Room temp is around 21c

Obviously temps could better but I want it barely audible.
 
CPU- 9900k @ 5ghz
GPU- 2080Ti at 2050mhz
Corsair 900D with 2x 480mm rads (one 60mm the other 37mm) and dual D5 pump.

Mine gets to around 40c. That’s with all fans at around 1200rpm constant. GPU itself gets up to a maximum of 49c usually after hours of maxed usage. CPU stays generally max of around 60c.

My pc is in a shut wall cupboard and the ambient gets up to around 30c after a prolonged period of gaming. As of the above it is shut with only a very minor air gap, temps I’m not too bothered as I’ve done all the above to keep it completely inaudible whatever the situation, gaming or otherwise.

Gone are the days of a pc on or under my desk due to size and noise.

One of the best decisions I’ve made tbh in terms of pc gaming. Keeps it ultra quiet, out of the way and there isn’t any dust build up at all. I also turn it on by a wireless remote so there are literal weeks where I don’t even look at the system :p.

Cooler Master H500M case, Gigabyte X570 Aorus Master Motherboard, AMD Ryzen 9 3900X, EVGA XC Ultra GeForce RTX 2080 TI in EK Waterblock, EK-KIT P360 Water Cooling loop, 4 x Cooler Master MF120R ARGB 59CFM fans as exhaust fans top and rear. GPU overclocked to 120%, CPU running overclock of 4ghz base (not played around with it yet).

I am seeing measured water DT of 10-12 deg C over ambient, so water is normally 38-40 deg C max during gaming in a small bedroom. GPU around 47-52 deg C and CPU has been up to 65 deg C at one point during 5 hours of gaming. I have been testing with different fan curves in order to keep noise to minimum with great results. Last night I moved my top exhaust fans as looking at fitting another 360x28mm radiator. Realistically, another radiator will probably only drop water DT 2 deg C without swapping out exhaust fans for more of the Varder high static pressure fans. Would love to get water DT down to nearer 5 deg C but at what cost? I dont mind blowing £150 on radiator, fans and fittings as it is my hobby but that will be the end of expenditure on current rig.
 
I decided to carry out more tests before committing to further purchases in order to reduce Delta-T. On my setup I have 4x120mm exhaust fans, 3 at top and one on rear. I have 3x120mm pulling inlet fans mounted on the rear of the radiator at the front of the case, and in front of the radiator I have 2x200mm fans in push configuration. The 2x200mm fans are not speed controlled and run at 100%. The 3x120mm inlet/radiator fans are controlled by water temperature sensor. The 4x120mm exhaust fans are controlled by motherboard temp sensor which is a few degrees above case internal air temps. The water pump speed is controlled by the CPU temperature sensor with a 5 second reading interval. For the tests, I ignore the temperature sensors and set the fans so they run at a constant throughout the duration of the test. My approach to the tests was to achieve the lowest Delta-T. I decided to keep the water pump and exhaust fans running at 20% for all tests, only changing the inlet/radiator fan speed in between each individual test, while allowing the system temps to lower back to a starting point of 2 degrees C Delta-T before starting the next test. I ran each test for a minimum of 30 minutes using the Heaven Benchmark and HWinfo64 to obtain recorded readings . At the end of each test I recorded fan speeds, temperatures including ambient, water, Delta-T (calculated), CPU and GPU (average and maximum) and finally noise in dB. I did increments of 10% on the inlet/radiator fans (starting at 30%) and after finding optimal values narrowed it down a bit further with 2% increments but that was unnecessary. So to my results. I found that over all of the tests the Delta-T achieved was between 7 and 13 degrees C. The optimal was with the inlet/radiator fans at 50% (1254rpm). Ambient=27c, Water=34c, Delta-T=7c, CPU=52c (max=56c), GPU=55c (max=59c), Noise=64dB (but I am not sure about noise as that seems high). The Delta-T of 13 degrees C was when fans were at 30% (slowest setting). When the fans were at 60% and 70% the Delta-T was 8 degrees C and the CPU and GPU temps were 1-2 degrees C higher than when at 50%, but the fan noise was starting to get noticeable. The next tests are to determine optimal pump speed to go with that inlet/radiator setting. Its all time consuming, but its fun. Sad me. LOL.
