4690k running too hot?
4690k running too hot?
Recently the temperatures have improved somewhat, hovering in the high 30s and reaching around 60 under load, about 70 with OCCT active. This applies while the pump runs in performance mode (around 3000rpm), and I've also recently added an extra intake fan, which seems to be beneficial. Operating at stock turbo speed (3.9GHz @ 1.16V).
If I switch the pump to quiet mode (17-1800 rpm), the idle rises to the low 50°C range, but OCCT still pushes the CPU to 85°C before shutting down.
Could this simply be the thermal compound settling in, or has my adjustments loosened something inside the pump to improve flow? The pump temperature now seldom exceeds 10°C above ambient (30-35°C), whereas previously it would reach 25°C (+45-55°C) above ambient.
Sorry for the messy note, I have too many moving parts to keep track of. I’m really considering getting a Noctua D15 next... it seems like a more stable option.
When I encountered a problem with my pump, I went through several troubleshooting steps. I believe there was a blockage. Initially, I replaced the thermal paste, which made it cooler for a while. After that, it warmed up again. I changed the paste once more, and it cooled down then heated up again. My thought was that removing the cooler might have pushed some particles into the tube, causing the blockage. Later, it would reoccur. I’m not certain about this, but Corsiar accepted the return, and I haven’t paid much attention to it. On my end, I noticed my pump was running a bit above 3000rpm in performance mode, which is higher than its rated speed. It never used to do that. I don’t know if the blockage increased pressure or if that affected the speed. I’m not sure about the details, but after changing coolers, the issue disappeared.
Thermal paste needs some time to set after application. Your temperatures are stable now. I switched to an AIO cooler long ago; air provides better cooling performance without the risk of fan failure, which is easy to fix. I use my [email protected] 1.26 volts with a Cryorig R1 cooler.
I understand. I'm not sure if the GTX has a better rating for pump speed, but it tends to stay around 3000 when in performance mode. It might have been having issues before, since I've mostly seen temperatures above 40°C, and it only started getting hotter recently, which means I had to lower my output.
Hopefully Corsair will respond soon, and thank you very much for your assistance (so far)!
Alright, so Corsair has now chosen not to assist me because the cooler was purchased from a second-hand computer. At the moment it seems to function properly, but if I manage to find a good deal on Black Friday, I'll replace it.
Sorry for not replying, Zerk—I think I wrote while you were responding! Yeah, I’m really keen on hassle-free ownership, especially since I’ve invested in all Noctua case fans which should maintain good airflow. My main concern is that if I opt for something like the NH-D15, my EVGA Hybrid radiator won’t fit (I’m also planning to replace it, but I’m tight on money). Maybe I could install it as a top outlet, though I’m not sure how much space a large CPU cooler would take in my case (CM Mastercase 5)?
So just as a happy(-ish) ending, I ended up getting an NH-D15, and I'm currently running at 4,4GHz@1,25V and barely touching 70c during Prime95 small FFTs, and the fans aren't even having to speed up! I never got 4,4 stable on the Corsair, so this is a bit of a revelation for me! Also a LOT quieter! Maybe I didn't lose the silicon lottery at all? I was also able to fit the GPU rad as a top exhaust, although I had to drop the push/pull config. Wish Noctua made GPU-coolers as well now...

Thank you guys again for all the help, and sorry for the rant, I'm just super happy now!
