As summer approaches, the overall temps are hopefully going up, but so are my system temps too. The new machine is fairly good, but will soon go back for a rebuild which they know about and have accepted.
Over the last two months, the average liquid temp has climbed from 32 to 41 degrees when running the sim and as the ambient temp rises further, so will the liquid temp. My question, is what would you all say that a maximum, sensible temp should be? The system currently uses a six fan push/pull for the radiator, three more at the front, two (soon to be three) exhausting at top and finally, the exhaust at rear. They are currently set to a mid to high speed setting. Thanks in advance for any reply.
No, it is liquid temp as reported by the LCD on the cooler and by the motherboard. GPU temps are in the 70s, but it is the water temp that I was thinking of. Ambient here in UK is only around 15 to 18 degrees at present, but if the vaunted British summer works for once, we could be in the high 20s on occasion and I could be simming in my shorts well before then.
I can check later for you, pretty much same setup, 12900k running on a H150I (but 280mm rad), along with a 3090ti FE (chucks most heat out the back)
Curious, why so many fans? More fans does not mean better cooling, you could be choking your machine as air is not flowing correctly, I have 2 at front pulling air in, 1 at the back for exhaust, 2 on the rad pulling air out from case over the rad out of the case.
I know for full fact my liquid temp will plateau at around 46deg (ambient of about 20deg) when leaving Cinebench r23 to run for half hour or so with the pump on its medium setting and fans at around 1350rpm, CPU will reach very high 80’s low 90’s. But that’s the CPU pulling 220w for that period of time. FS2020 hardly uses much at all, majority of time the CPU sits in the 50deg mark.
Oddly, that is why it is going for rebuild. It was all supposed to run through Icue and it doesn’t. Like, at all. The whole question of blocking and efficient airflow has been with me since day 1 and I think that the liquid temp could possibly be an indication of this.
Absolutely fine. Ultimately youn just need a heat gradient for the heat to flow down from the CPU. If liquid temps rise too much (i.e. to the point where CPUs temps run beyond 90C, which is likely never in this sim since it’s not fully loading a 12900K), add a little fan to the fan curve to cool it more.
I would say anything between 30 to 40c under load is respectable, but that’s highly dependent on system setup and radiator size. I would not dwell too much on fluid temperature. As long as your processor temperatures are in the good range, don’t worry about it.
In reply to this, sorry took so long, but after an hours worth of playing, my coolant reached 36deg (ambient is 20), CPU averages 51deg. This is on a 12900k (no overclock or undervolt), 3090ti (exhausts out the back as its an FE card). I realised I am using a H115I (not the H150I) with a 280mm rad.
Thanks a lot for your input, it is appreciated! Just got back down from my own PC and got a liquid temp of 46, but the office is warm so I cant be surprised really. Hopefully, it will improve a lot on the rebuild, so the time since new hasnt been wasted. Just trying to find the areas that need addressing.
