Hello Everyone,

Noobie here.
What is the proper temperature range under gaming load for liquid cooled GPU and CPU?

Just my guess:
Loaded Gpu: 45-60C?
Loaded Cpu: 45-60C?

And how about for Idle temperature?

and again just my guess:
Idle Gpu: 20-30C?
Idle Cpu: 20-30C?

Parts are:
RTX 4090/4080ti with EK block
i7 13700k/14700k with EK block
480mm Heatkiller Rad
360mm Heatkiller Rad
Bitspower D5 Pump Combo

Thanks!
 
When using liquid cooling systems for electronic components, it's crucial to maintain appropriate operating temperatures to ensure the components' reliability and longevity. Liquid cooling is an effective method for dissipating heat, but it's important to understand the acceptable temperature ranges for different components. Here are some general guidelines for acceptable component temperatures under liquid cooling:

1. Central Processing Unit (CPU):

Idle Temperature: Under liquid cooling, CPUs typically run at idle temperatures between 25°C to 35°C.
Load Temperature: Under heavy load, such as gaming or rendering, the CPU should generally stay within the range of 50°C to 70°C.
2. Graphics Processing Unit (GPU):

Idle Temperature: Similar to CPUs, GPUs under liquid cooling should maintain idle temperatures around 25°C to 35°C.
Load Temperature: For gaming and other graphics-intensive tasks, GPUs can operate at load temperatures of 45°C to 75°C.
3. Motherboard Components (VRMs, Chipsets, etc.):

Under liquid cooling, motherboard components usually remain within the range of 30°C to 50°C. It's important to monitor the specific components on your motherboard for variations in temperature.
4. Memory (RAM):

RAM modules often operate at temperatures similar to the motherboard components, with acceptable temperatures ranging from 30°C to 50°C.
5. Storage Devices (SSDs and HDDs):

Storage devices tend to be less sensitive to temperature variations. They can operate efficiently at temperatures of 25°C to 45°C.
6. Power Supply Unit (PSU):

PSUs generate heat but are not typically liquid-cooled. They have their own cooling mechanisms. It's essential to ensure the PSU has adequate airflow to maintain an acceptable temperature range, typically between 40°C to 60°C.

To add to what pronashit posted: It depends heavily on your water temp and ambient room temps.
Thanks Alot Guys!
 
You have to look at load temps, where you gain the most compared to air cooling
you win 10/20c according to airblow/radiator/fans/cooling block
+ setup of voltage in bios/overclock
and then maybe a little noise

Lot of incorrect info there, especially seeing as Raptor Lake can run up to 100C under intense workloads with standard cooling.

Looks like an AI reply. I'd bet on it since that's his only post on the account.

@OP, the temperature is dependent on ambient temp. Live in SA and you have constant 40c ambient? You won't be able to compare your temps to someone in Canada.
 
It... honestly doesn't matter unless you're hitting 80-85C or above under water on load.
If you are, that means you're most likely heavily pushing the chips on purpose, which is your own decision to make.
Otherwise, at stock, those temps should almost never happen with a typical custom loop.

I smell AI/ChatGPT.
 
GPU rarely goes more than 15C above water temp, even on unlimited power VBIOS.

CPU can easily go 50C above water temp, because the main bottleneck here is heat transfer from the die into the water
 
I'm fully watercooled with 3x 480mm radiators, 2x d5 pumps, and a total of 13 fans. Of those 13 fans, 12 of them are set to intake and placed over radiators, with 1 fan set to exhaust in back of case. I am using a 13900KS and RTX 4090 My ambient water temp is a consistent 32c and never really fluctuates as I run my centralized air through an AI suite that maintains my home temperature very well. My CPU at idle is around 38c and will ramp to as high as 88c under full load. My GPU at idle is around 35c and will ramp to 55c under full load with hotspot going to 65c My 8200 MT/s 48GB DDR5 memory modules reach 60c under full load conditions (mem test 5)

Do not buy the EK GPU block for this gen unless it's too late. There was an over 10C difference at full load/power limit between the EK block I bought at first and the Heatkiller I replaced it with (reseated it like 4 time, changed pads out etc. it just sucked).

In general:

Loaded GPU temp should be somewhere between 10-25C (it shouldn't be 25C but those EK blocks suck) above your water temp depending on your block/power limit. Without knowing your ambient/fan speeds/overclock etc it's hard to say what kind of temps you'll see. IE if you have a 20C ambient and run your fans full blast at an 80% PL, you might stay in the low 30's. If you don't mess with clocks or PL, and run your fans at like 1K RPM, then my guess is gonna be high 40's to low 50's with that block.

CPU is gonna have a lot more variables depending on what you do. but those things run hot, and whatever temps you see people getting on 360 AIO's is probably similar to what you're going to get.


For reference, I have a 4090 FE with the Heatkiller. It's in an 011D mini with a 360 and 280 rad. Fans run at 1000rpm. ambient is about 20C, and with an 80% PL I think the highest temp I've seen was low 40's. CPU is a 5800X3D

32C seems pretty high for an ambient temp. What's your delta T?
 
Lot of incorrect info there, especially seeing as Raptor Lake can run up to 100C under intense workloads with standard cooling.
You're in the water cooling section. With any sufficient water cooling build your cpu should never see 100C unless you're throwing suicide voltages at it. Doesnt matter what it is rated to do in a standard vanilla world because that's not what OP is asking about.
 
My system has a delta T of about 4C at ambient room temp of 22c . 13900@ 5.8 Ghz, RTX 2080. Total watt usage under full load 580Watt . CPU temp Max 85C and 50C for the RTX2080 all under full load.Under norlam load temps settle usualy to about 32C.

I have a i7-13700K + EKWB Velocity2 WB and i have a MSI RTX 4090 Gaming X Trio + EKWB Vector2 WB (no active WB)

These Raptor Lake cpu's can run HOT more so then other previous cpu's what used to be average temps for cpu's back then DOES NOT apply to Raptor Lake dang these things can get hot with air cooling....ie higher then 100c at max load...gosh...

Using two external Aquacomputer Airplex Modularity System radiators 840 these are huge rads and DUAL D5 pumps at setting 4.
Room temp = 21c
Water temp = 24.9c

CPU runs at PL-1 125w and PL-2 253w and a small undervolt (-0.100v) for day to day tasks incl gaming.
BUT for testing with cpu i used FULL intel spec. As well as the RTX4090 at FULL stock ie 100% PL for testing only.

i7-13700k IDLE temp = 32c
RTX 4090 IDLE temp = 25c

Cinebench CPU with FULL intel spec = PL-1 253w and PL-2 253w = max temp 74c (without undervolt = 85c).
Cinebench GPU (2024) GPU core temp 38c, MEM temp 48c HOTSPOT temp 44.8c

3Dmark - Time Spy Extreme 4k D12 Benchmark = GPU core 49c, MEM temp 44c, HOTSPOT 61c (used to be lower temp GPU core to Hotspot was beginning around 8c/9c probably my Gelid GC Extreme has smallish "pump out" i HATE this man with some pastes!! But still good temp from core to hotspot next time i might use PTM7950 = no pump out)

Gaming:
Cyberpunk 2077 benchmark: (Ultra settings, DLSS Quality, RT Ultra everything else = highest)

CPU = average 51c max 60c
GPU at 100% PL= Average 40c Benchmark: GPU core 43c, MEM temp 44c, HOTSPOT 51c (100% PL usually i play at 70% PL which also gives lower temps and less power draw)

Helldivers 2 gameplay GPU at 100% PL: (game is pretty tasking on cpu)

CPU average 47c - 58c
GPU average 36c - 42c

TIP:
If you use the RTX4090 i strongly advise you to play ALWAYS at 70% PL (MSI Afterburner) why???
Because look at the RTX4080 you see FAR less ISSUES with these cards ie no melting BS of 12pin cable why? Because of the 350w max. RTX4090 can go as high as 600w!! This is just to much for the kind of poorly designed 12pin small cable also it runs at ALMOST max amp ie just 1AMP short of max! Hence i would advice to run the RTX4090 at 70% PL you only lose about 8% performance big deal...plus also do FPS cap! If you play NON competitive games and you still got HIGH FPS even with everything cranked up to highest then do a FPS cap of around 70 - 80 fps! This also reduces quite some wattage! Cyberpunk 2077 with the above options ie 70% PL and fps cap at 70fps @4k= 310wat. Also never use a 90 degree power adapter this can cause big issues. We all know these DAMN companies don't care about their honoring warranties they will BLAME it on you most of the times or send you a crappy "refurbished" product that has other issues...Be wise pronlong the GPU life span use 70% PL and fps cap if needed! You still have everything on eye candy ie max settings. Obviously the WB will also help prolong life with cooler temps.

Also even tho the EKWB cpu and gpu blocks are pretty decent but there are BETTER blocks at lower price look at Aquacomputer, Watercool, Optimus, Alphacool (their GPU core versions).

Hope this helps.
