[SOLVED] CPU Temperature too high even with AIO?

[Slyver1080]

Good evening or morning, i have a question regarding what is of the title, i have a Ryzen 5 2600 with an AIO, today i though of checking the temp and noticed that it was around 55C-48C while in game it goes to 70C. Now considering that where i live the heat is horrible, can get up to 48C, 34C at night with high humidity, does this ambient temperature affects at all? Or should I consider replacing the AIO?

Edit: the AIO is brand new i got it like 2 months ago, is the MSI MAG Core liquid 240R, while PC cabinet is the MSI MPG Sekira 100R

Maybe try locking the voltage. Try 3.9 GHz @ 1300mV and keep going lower until you crash in a benchmark(Cinebench) then go with the last stable voltage and test in other benchmarks and games.

Liquid cooling is not magic.

Ambient temperature has a huge effect. If the room temp is high, the system temp will be correspondingly high.

Your system getting to 70C is nothing out of the ordinary.

Hi there Slyver1080. Welcome to the community. Yeah, ambient surround temperature will affect your CPU temperatures. Ryzen processors does have an aggressive core boost algorithm by default and they boosts nearly to max core frequency for simpler tasks too. The temperatures you mentioned are well below max temps and are considered safe for operating of processor. Can you please tell the details of your AIO and your PC Cabinet. If AIO is 3-4 years old then you should think of refilling it with a coolant likely distilled water.

Yeah i just edit the post with said information

Typical throttling temps start at the 80s and a 70 c running temp while gaming is normal. I would not worry about it unless something has changed. If you were running low 30s before with a 50 top out then yes I would definitely replace the cooler. Pumps and exchangers can degrade over time. The majority of coolers are ambient exchange coolers, so the colder your operating conditions are the cooler your CPU will run. Cooler designs are limited to the temperature delta and exchange surface area. So while water cooling has a better potential to keep the thermal exchanger attached to the CPU closer to ambient the chip underneath will still heat up quite a bit.

There was a suggestion to refill your AIO with distilled water. First off I would never break open an AIO to change fluid. Replace the AIO. All you will end up doing is either air locking the system (bad) or leaking fluid on components (really bad). Further more if you have a custom water loop intermittent fluid replacement is a good idea, but never with straight distilled water. There are coolant additives that must go into the loop that contain corrosion inhibitors. Many components contain aluminum and running distilled water (which is slightly acidic) will cause corrosion. Once the distilled water has some ions picked up in it from that corrosion it will create a current loop and electrolysis will start up. This corrosion will increase the impeller to housing dimension in your pump causing low flow and reduce the heat exchange capability in blocks and radiators with buildup. Go long enough and it could also pinhole aluminum tubing in the radiators (leaks) too. The reason that coolant replacement is suggested is to replenish the corrosion inhibitors to prevent this mess. The inhibitors are sacrificial and degrade over time. If you put distilled water in instead of coolant you have actually made things much worse.

Bad idea with an AIO system.

Never refill an AIO with only water, not even distilled water. You have to use a glycol solution with anti-corrosive, and as well an anti-biological so that nothing starts 'growing' in the loop. And besides, an old unit that's lost cooling effectiveness would probably be from crud that clogs the microfins in the water block. You have to completely disassemble to get to that and clean it out.

Not that this is relevant as OP said his AIO is only a few months old.

MSI MAG Core liquid 240R

Another one of these PIR units... I think I already know where this is going, though the Sekira 100R doesn't help things either.
Just to be sure, can I ask where did you mount this?

What's a PIR unit? Pump In Radiator?

Ok...let's say you're CPU temp is getting to 70C with ambient at 48C. Now let's say you reduce ambient to a much more comfortable 30C. With that change alone your CPU temp will drop to a much more reasonable (70-18) or 52C or so.

Yes, it works like that: you can't cool better than the ambient air being used for cooling without some sort of a phase change process being involved. It may not be feasible but a room air conditioner that keeps the local (room) environment at 25-30C would be the phase change process involved.

Computing centers are kept chilled for a reason, and it's not because they overclock.

Yes. I was being lazy.

Well to respond to this before the heat season hit it was around 35c or so max at 50 when gaming once the heat season came i saw it go to 45 idle and 70c while gaming, given though room temp was at 38 or so and humidity at 37% so it was hot overall

I mount it on the front, fans sucking the air first then throught radiator

 

[Phaaze88]

Well, at least you don't have it mounted at the top, but the way the above is worded has me lost.
If I've read this right - the fans are pushing air through the radiator into the chassis? If so, you should move the fans to the opposite side of the radiator to pull air inside.
The solid front panel of the Sekira 100R is a big obstacle, and you're just choking the fans by having them that close. Position them further away from that wall so they have more breathing room, and thus have an easier time trying to bring air in.

Ah yes what i mean is that yes i put the fans first, so they are attached to the case first and then is the radiator behind them

 

[Phaaze88]

~Yeah, it would be easier on the fans if they were behind the radiator pulling air inside instead.

Hmmm ok i will try that then...even though I never done this but shouldn't be that hard is just unscrewing and screwing again

I am in the US so forgive my Celcius conversion but if your room is running that hot assuming normal room temp is in the 20s I would expect that much of a change in operating when ambient increased from 20 to 38. Humidity doesn't effect heat transfer on a dry radiator the same way it does people so it is pretty linear. We sweat and use the heat of evaporation to cool. Radiators are just exchanging to the air.

Greetings Drea,
You might not had understood my words. I said to use a coolant along with distilled water. I mean corsair and other companys sell coolant filled tubes which can be added to cooling loop which does have anti-freezing and anti-corrosive properties. I mean distilled water doesn't contain any saliva or any enzymes right? It is "DISTILLED"

 

[drea.drechsler]

Greetings Drea,

That would certainly do well...to refill my AIO I used automotive glycol antifreeze in about a 30% solution with distilled water. It doesn't need to protect against freezing, it's mainly for the additive package they have that includes anti-corrosives and anti-bacterials.

Distilled water has little to no dissolved minerals that can precipitate out and cause problems. But unless the distilled water you buy is medical grade and you use sterile procedures it's more than likely anaerobic organisms that are all around us will be passed into the loop when you do it.

One can only expect so much of a moderate CPU temp if ambient room temps are 35-38C, if I interpreted the environment correctly...; an AIO is no 'super CPU chilling unit', and, temps normally run a certain spread above whatever ambient temps are.
