1. That's your biggest hurdle...the mental one - getting used to the fact that letting your cpu run that hot is ok. Once you make good with that, things would be a lot easier for you.
2. Thermal paste or TIM (Thermal Interface Material). Thermal pastes are all within a couple/few of C, really. Plenty of reviews out there. Look up, "thermal paste roundup" and check some of those out to see. Your better off perfecting your application amd mount than you are to pay a premium for a paste that is 1.5C better.
Noted on thermal paste. I have never done this myself, and was told before not to use a youtube video to learn, is that true? haha. I will just use the one from cooler master as I still have it.
Rule of thumb is that a good AIO cooler with 240mm radiator will give temps about 1-3c better than the best air coolers (e.g. Noctua NH-D15). Your case also will accommodate a 360mm AIO radiator which will give you still a little better cooling. Going with the best AIO cooling solution available may give you 5-10c but there are go guarantees. The efficiency of whatever cooling solution you deploy is really hurt by your high ambient temps.
I was going to go with the 360mm ones as it would fit, as that is pretty much what I have now, There is plenty of space for three front fans. I think the D15 is quite big, each fan is 140mm, that would be pushing it, though with Noctua design it probably would fit.
I meant the Noctua NH-U14S. Sorry for the typo.
I wasn't planning on running a CPU for 10 years, but I still have my X5690. An AIO or CLC or whatever will be awesome for about 18-24 months, after that you will notice its performance start to taper off, especially with a CPU like yours that puts out real heat, quad cores are relatively easy to cool. I went back to air and I haven't really looked back. I still get great performance and can max my cpu in clocks, and voltage (1.6v), and its quiet, until I turn my fans up during some benches, or certain stress testing. Even my 3770K took 1.525v with air. Didn't like it much, but it still took it. Its nice not having to worry.
So what you are telling me is that either Fan or Water, after 18-24 months it is time to swap out the fans anyway, right? Or do you mean the CPU is going to stop performing like it does now? I am guessing you mean the CPU performance.
You can expect about 3°C difference between the U12A with 2 fans and the U12S with 2 fans ( U12S comes with 1 fan as a standard) where U12S is already around 5-6°C better than the Hyper 212. Depends on the CPU (more like core/die size etc), U12A can perform even close to the 280 AIO and beats popular 240 AIO, the same as the D15 which is significantly larger cooler. The D15 is barely better than the U12A. Count maybe 2°C difference in most scenarios but can be some more, depends on the CPU.
Temps above are from my tests on all these coolers but I was using mostly Ryzen 3700X, 3900X, and Intel 9700K/9900K. Results highly vary depends on the CPU and its die size. I also can be slightly wrong but this is how I remember my results.
Actually, I saw the thread title and I thought it's a bigger problem. 80°C is quite low for that setup. Most new Intel CPUs go up to 90-95°C on similar cooling so for sure there is good airflow and I wouldn't worry about anything in this PC. It's nearly impossible to keep these chips below 80°C under load using a typical air/water setup. Even if you use higher series cooler then you won't see constant ~70°C under full CPU load. My tests on the 9700K were giving me higher temps on better coolers, not to mention 9900K.
I may let this go for awhile as is, and then after 1-2 years replace the CM with the Noctua, or depending on how hot this summer gets, if indoor temps reach 30+C then I am kinda screwed because at night I won't be able to run but maybe 20% of CPU without going over 80C. It's pushing it now as it is. But it is interesting to see that 5-6C, and a replacement of the back exhaust fan may add another 1C. Which is pretty significant. I did have a bigger problem at the beginning of all of this, but I did not post to the forums right away, I tried to resolve the problem for weeks on my own. One of the biggest issues that I had that made temps spike to the 90s was ASUS' crummy AU suite fan controller. The original one with the system didn't even have a fan controller. The fans would just go based on temp of the CPU, but as you can guess it delayed high RPM causing peaks over 90C. I contacted ASUS and told them I want FULL FAN control, and they gave me a link to an update. Where I can set 3 MB controllers for 100% RPM, which is what it runs at 24 hours a day now. DB is around 30 with all that. I have 10 fans in my pc, so 30 isn't too horrible. But much louder than it originally was.
I still feel 80C is high, but yes, I know these particular chips run extremely hot. 3 year warranty, but hoping to get at least 5-10 out of it, but running it like it is now, I have no idea.
My CPU was spiking over 90C weeks ago, and after tinkering with things and getting more fans installed and adjusting the direction of them, seems to have helped significantly.
I want to get a smoke machine to see the air flow through the machine to see if what I have already done is the best, but they run about 100-200 bucks, so an incense stick will probably be the other option.
