Is 80c on the CPU very bad?

[ravenjedmanicdao]

Hello all, so I just recently bought the i7 4770 second hand as a replacement for my i5 4440 so I can run the GTX 1080. I've applied the usual standard amount of thermal paste (AS5) and tested it on CPU demanding games such as GTA 5. After a while, the temperature climbs up to a maximum 80c, which really worries me because my old i5 usually reaches up to 60-70.

The cooler I use is a DeepCool Gammaxx 200T, which I feel was mediocre, so I ordered the CM Hyper 212x, so I am hoping that helps. I also bought Corsair's SP120 performance edition fans with 60+ CFM. I decided to try out a different thermal paste, so I got the Thermal Grizzly Kryonaut, which I hope is better.

Anyway, is my i7's max temperature of 80c extremely bad? Because I am currently facing fresh 40-44 celsius days (Australia) right now.

your new CPU have more frequency speed and threads than your previous i5. naturally it will get relatively hotter very quickly. and 80C on peak loads is pretty normal with the type of cooler you have. nothing to worry here.

80C is very toasty. I have a Ryzen 7 1800x. I have it overclocked to 4.0 Ghz, even when I render video it doesn't hit 80C. I'm using a Corsair H100i AIO water cooler.

My cpu idles around 35-40C. Its render temps are about 50-55C.

I derped and skimmed over your upgraded coolers. BUT! air cooler can only do so much and the coolers you've chosen aren't that much larger in mass.

Perhaps check your thermal paste. Your cooler may not be conducting heat properly. Possibly invest in a more efficient cooler.

80°C for a gaming load isn't good, especially at stock speeds, but most of that is attributable to the cpu cooler, it's ok for an i5 @4 threads, but the Hyperthreading of an i7 is a whole different beastie.
Yes, the kryonaut is a far better paste, apart from the fact it won't dry out due to heat cycles like the AS5 does.
Yes, the hyper212x is a better cooler than the gammax 200t, and should be enough for the 4770. But you'll only see @ a 10°C drop or so at best under the same conditions as earlier testing as it's still just a 140w budget cooler on a @150w peak cpu. I'd not to run too many real stress tests such as Aida 64, Intel burn, Prime95 or occt or temps will skyrocket. Heavy gaming temps usually run @70% of possible max, so if gaming is dropped to 70°C, you'll still possibly hit 100°C under max stress.

Hey all, thanks for the replies. I have replaced my cooler to the Hyper 212X, and with Thermal Grizzly Kryonaut, now temps never reach above 65c (Tested for 1 hour in Prime95, while I was away), so hopefully that's better.

Much better. But be careful of Prime95. It's got 2 different versions, old and new. Old (26.6 and prior) and new (above 26.6). Old p95 uses very little AVX instructions, so is well adapted to running gaming max temp scenarios as games really don't use AVX either. New p95 uses considerably more AVX so is better suited for an all purpose or editing/rendering pc where programs will be using AVX. Also p95 uses 3 different types of tests, small fft is all cpu, there's almost no ram taken into the mix, so provides a solid steady 100% load, which is perfect for max temps baselines. Large fft uses a lot of ram, so spikes workloads, bouncing between @60% and 100%, so is better suited for stability testing than temps. Blend is a mix of both, but being a jack-of-all-trades test, doesn't quite give max baselines or really push stability.

Best for temp baselines at max loads as compared to gaming is Prime95 v26.6, small fft. 20 mins is fine for aircoolers, 1hr for AIO's/liquid cooling.

If you can hit @70°C with p95 26.6, small fft then you'll never hit over that no matter what game, and if you do it's only because the cpu cooler is dirty. I use that in conjunction with Realtemp, which runs constantly in the Taskbar, so can tell exactly when my cooler is in need of maintenance as gaming temps climb towards the p95 baseline (happens to be 67°C for me).
