Corsair watercooling overhgeating 65c

[Gisborne]

Entire PC was flashing red, i didnt know why, just seen its because coolant is overheating in fail safe mode at 65c??? I thought game was causing rbg effects lol but the game is cooking my CPU. anyone else got this issue with corsair AIO?

[ppRogue1]

I assume you mean a Corsair AIO cooler like the H100 or H150? If so, you've probably hit the 65c emergency alert threshold for coolant temperature (as opposed to CPU temperature). You shouldn't be hitting that all, even if you leave your PC running a synthetic benchmark like OCCT all day. I'd check that the pump hasn't stopped.

its only doing it in this game? never ever had this issue before, only when i started SM2 today. i shut game down 15 min ago tis still hovering about 45c and flashing red.

all fans and pump RPM are working and fluxing so nothing seems to have stopped, it is warm asf in my bedroom like, window is open tho, not much else i can do...

same, this game makes my fans run wild cause the cpu just instantly spikes to 90° and beyond. it gets cooleddown, but i had not this issue in any other game so far.

@OP: What exact CPU are you running?

To debug the problem: Get a tool like prime95 etc. that gets your CPU to 100% load and check that your cooling can actually handle your CPU at full power. A properly sized cooling solution should handle 100% load for days without overheating.
Also - a game can't stress a CPU beyond it's normal limits and all halfway moderns CPUs will drop their multiplier in order not to overheat.
We will see this behavior more often as games finally start to utilize all those cores we have at once.

13700k and h115i

I'm testing undervoltong now, I can bench and test full load but it's the coolant thays overheating not the cpu?

the coolant is running 50c on desktop with no load.

Ok got the 13700k as well - desktop idle my coolant stays around 2-3C above ambient. So right now around 27-28C.

[WASHED UP 1.6 SCRUB]

Game is definitely at fault here.

4090, 7800XD: Both with full custom loop. Coolant for CPU/GPU curves set so the coolant is at 25C

GPU temps are fine @ 40-45C; however, CPU temps were reaching 90C. I changed the curves on the fans and settled at 80C. I have an extremely over-the-top rig and never have I reached these temps except when I am benchmarking and pushing the limits via overclocking.

[Vali_Lutzifer]

my CPU only goes to 100 degrees with the game otherwise never

My coolant is 45 to 50 and it's might here and not thay warm, nowhere near 50c lol.

If the coolant on a Corsair AIO is at 50c when the PC is idle on the desktop, something is not working properly. It should be low to mid 30s in most situations, maybe going to high 30s if the room is particularly hot. I suspect something may be stuck that's blocking the coolant flow. At any rate, that looks like a hardware problem.

The highest I've ever seen the coolant go was 48c, playing Total War: Warhammer 3 (which hammers both CPU and GPU) on a hot summer day.

13900k here at 5.7GHz / 1.4v delidded, custom copper ihs on a crazy custom loop (4 rads, 3 of which are 480x45) and the cpu sits between 80 and 90c, that's with fps locked to 120.

Kind of crazy what it's doing to the cpu tbh.

I mean my pc was in fail most with the coolant at 65c playing sm2 it's never done that before. I undervimted cpu and tested game again and cpu was no longer at 100c, don't know if I mentioned thay I saw a gameplay video I took and it shows cpu at 100c, which could explain the crazy coolant heat?

[^9Iceman]

Yeah, I have the same issue. I can run everything on max, Tsushima, Deadspace and what not and my rig won't go over 50-55 celsius. This one, 75-85 celsius. Seems something is broken how the game utilises cores.

It might be that something's just now failed. I've had the pump go wonky on a Corsair AIO once before. It absolutely should not have a coolant temp of 50c on desktop. Mine's currently at 33.8c in a room that's 26c.

so ive just been watching youtube in bed for an hour or two, returned to pc to check temps and room is cool and temp outside is 17c, my cpu is 43c and my coolant is 44c
