[SOLVED] Cpu temperature trouble

[Cerapheir]

Hi , I am having issues with the temperature of my Cpu and I don't know if it works as it supposed to or not.
So my Cpu temp go a bit like this :

• Idle on desktop 0 window open 35 ° c
• Internet Browser 47°c
• Multiplayer Games 55-67°c
• Solo (more heavier games) 60-80 ° c

Now I have a water cooling system from thermaltake and when I ask my friends who have regular fan cooling system they have very low temperature in those different categories as opposed to mine.

Note : I have also those programs installed with the motherboard , Dragon center and MSI Gaming APP
-No presence of malware or trojan
-New cooling tubes and recently cleaned PC

Hi

How is your Bios setted? May you post a screen about voltages so i can check.

Now I have a water cooling system from thermaltake and when I ask my friends who have regular fan cooling system they have very low temperature in those different categories as opposed to mine.

Those temperatures seem fine.
Your friends probably are using different cpus.

Oh - you have custom loop watercooling.
So it is pumping water into GPU first, heating up the water and then pumping into CPU?

SkyNetRising So you are saying that for the same game my friend having 30° c with just fan and me being at 60 °c with water cooling is normal ? How do I check that ?

edit : Yes he's running with an intel I5/My Gpu doesn't seems to suffer of the same problem as my Cpu.

 

[SkyNetRising]

Who built your custom loop?
If you did it yourself, you should know water-flow direction.

Looks like your pump/reservoir is either PR22-D5 or PR15-D5.
Then water would flow this way:

 

[SkyNetRising]

Your cpu and gpu are in same loop. They have same temperature and are heating up each other.

SkyNetRising -> It's was built by msi custom shop

Temp CPUvsGPU

Cpu and gpu will always have different temps at idle. The gpu is direct die cooled, and reacts to the graphics load, the cpu has an IHS and crappy Intel paste and reacts to code loads. Which are entirely different loads.

A loop works on combined load according to cooling potential, and with a 360mm rad, that's close to 400w+. Run flat out, your pc will be looking at 300w range, so there's room.

Common mistake is coolant temps, and how it works. It's not aircooling. Take an empty pan, stick it on a burner, pan surface gets instantly hot in response to the heat output of the burner. That's aircooling. Put a decent amount of water in the pan, and even though there's the same thermal wattage transmission, the water doesn't get instantly hot. That's how a loop works, the liquid absorbs the wattage, from everything and puts it into the radiator which dissipates that energy. Difference of what goes into the rad and what comes out is around 1-3°C, which is why it doesn't make a difference as to order, you aren't putting 80°C fluid from the gpu into the cpu, it's pretty much the same temp going into any component.

Fix the pump speeds. That's way too low rpm on that curve, there's very little flow. Liquid cooling takes 1/2 hr+ to equalize, so anything during that time will show higher temps than normal, it's only after the coolant equalizers that temps will settle down. So if you don't get that liquid moving through the rad, it's going to retain too much wattage, less is absorbed, temps go up.

 

[Cerapheir]

Well , can you guide me through setting the rpm then if it's the issue.
I'm kinda of bummed out , I thought water-cooling was suppose to be way more efficient than fan-cooling.
The fact is I've seen everywhere that hitting 70°c and higher on the CPU isn't suppose to be normal; I mean I can of understand with highly demanding software of game but when i am at 60 °C on direct 9 or 11 game , I just don't get it.
I'm grateful for all the answer but no one actually told me if the settings were off or if it was a component issue (pump , liquid or fan ) and how to fix them.

 

[Karadjgne]

Liquid cooling, whether aio or loop has been said to be the same as aircooling. They aren't, they are opposites that happen to end up with similar results.

Aircooling is all about maximums and monimums, and not letting the heat get there, by speeding up fans to shove more air, faster and harder over the surface areas of the heatsink. The only similarity between air and liquid is at the radiator itself, how that energy gets there isn't. Nor is how it's handled in between.

Liquid cooling is about averages, with coolant temp and flow rates being more important than fan speeds. I'd start your pump curve at closer to 40-50% minimums, not 20%, and hitting 100% by the time the cpu is hitting 55°C (ish). From what I see, you aren't getting full loop flow until the cpu is hitting @ 90%C, which is handicapping its ability. That's like an Olympic runner doing the 100yrd dash and not hitting full speed until the last 10ft, and wondering why he came in last place.

 

[Cerapheir]

I have modified the bios settings like you said , it is indeed a bit better.
I still find odd that the temp go up so quickly and for not a great deal , like at the moment Im at 16 % cpu usage only and 30 % memory usage and I m already at 48-52 °c.
