Does anybody have any tips for improving PC cooling with no effort at all, specifically of the CPU? I have a factory OCed Intel i7 6700 running at 4.0 GHz (actually according to monitoring programs it's typically going up to 4.2 GHz, but anyway). It has a stock cooler which is supposed to be very good, from what I understand, but lately has been getting a bit hot. I noticed some graphics artefacts, which I think are actually a software problem rather than hardware failure (they're not persistent enough for hardware IME, and even if it is, it's unlikely to be the CPU as there's been no other trouble with e.g. software crashes or blue screens) but it did lead me to check on the hardware and I was a bit alarmed to see the CPU was regularly hitting 100⁰C under load, which is not awesome. I've vacuumed out its heat sink (yeah I know... I grounded myself FWIW), removed the dust from the fan intakes/exhausts and put the side-panel back on (!) but it's still going up to 82⁰C, which is still not optimal, and I dare say under prolonged load it may go higher. Idle temperatures are okay at 35-40⁰, and the GPU (Radeon R9 390) idles at the low 30s and tops out at the mid 60s which is what I would expect to see, so I'm not really sure what's the deal with the CPU. Its fan speed seems a little low to me at 2,200 rpm, though there's no option to increase it in the BIOS except to change the profile for when 100% fan speed kicks in, so I've reduced the temperature at which it maxes out, but I can't see it'll make any difference under continuous load. And "continuous load" is still only 30% for the package as a whole when running FO4, even with threading turned on, since most of the workload is still done by one thread. I have hyperthreading turned off because I don't see the point: not sure what effect this has on temperature, but as far as I'm concerned it just duplicates the OS's multitasking efforts without having enough information to do so as effectively. But that's another matter. I guess I don't want to go to a huge amount of effort to improve it, but I don't want my CPU's life to be shortened (not that I've ever experienced one actually die on me in the 35+ years I've been using small computers) and nor do I want to enjoy any "juddering" as the CPU's equivalent of a rev limiter kicks in. But largely it just annoys me because it shouldn't be like that. I'm guessing that realistically I need to be looking at better case fans and/or a better CPU cooler, though both are a fair bit of effort, particularly the latter, and it's so hard to choose something that's actually more effective as so much after-market stuff is a classic case of "all mouth and no trousers". I was wondering if anybody had any thoughts. Especially of the labour-saving variety.
