My CPU cooler is way too loud, in the BIOS it runs at 1400 RPM but it gets louder when I enter into Windows and even louder when I start gaming. I have an intel core i7 7700k processor, not overclocked and running at an average of 30-40 degrees. It is very annoying, if you have a solution please let me know. I am considering replacing it with a Cryorig H7 Quad Lumi, should I go for it instead? I've been searching the net for hours now and still couldn't find a solution.

The hyper212 is a 140w budget cooler. That means it'll handle @140w worth of cpu heat output at maximum. The i7-7700k is a 100w cpu. At 4c/4t under nominal loads. Once you enable HT, and start loading down 8threads, that'll change. Vcore having much to do with the heat output, some cpus run very high stock voltages, as high as 1.4v, which is the cpus limit according to Intel specs. In bios there's no control whatsoever other than bios own settings, which will enable HT and run all 8 threads under load, so you can expect not only higher temps than normal OS operating temps, but 0 ability to change much, if anything. Bios temps themselves are only important if going above and beyond any reasonable output, if you are seeing temps in the...


Set a custom fan curve in the bios for your CPU, it will be nice and quite. 212 evo here, RPM never goes above 600rpm unless my cpu reaches 70c. Which never happens with gaming.
 
50-60 degrees while playing. I tried setting up the custom fan curve in the bios which proved to be effective but only while browsing the net and doing other stuff. As soon as I start playing the fan just speeds up and it doesn't seem to be getting slower even tough I am not playing anymore. As I am writing this sentence the CPU is sitting at 37 degrees but the fan is still noisy.
 


I just got a Hyper 212 EVO on my new build and it was annoyingly loud. On idle it was fine but whenever I do any task it would ramp up and sound like a turbine. Maybe a custom curve could have eased up the rpm and been less annoying. Replaced with Corsair Air Series SP120 120mm PWM High Performance Edition High Static Pressure Fan. This fan is really awesome and very quiet! IMO the stock fan is inferior.

Bios temps themselves are only important if going above and beyond any reasonable output, if you are seeing temps in the 90's for instance, then yes there's an issue, but anything under @70°C is absolutely normal. The cpu fan will respond according to bios settings and it's curve settings until the OS loads and changes that, so high fan speeds are normal too.

So you have the highest performance, hottest running, Intel lga1151 cpu and slapped a budget cooler on it that's barely over design specs for nominal usage. Add in the fact that windows responds to almost instant changes in cpu heat but physically takes longer due to mechanical process, and you get a fan that constantly ramps up and down.
To adjust fan curves is recommended, but they need to be set sharp, can't be a gradual curve, and mobo software or SpeedFan is best suited for this, bios only changes end points not the middle. You'll need to set the curve to remain below 1000 rpm under @60°C and a sharp climb to 100%duty cycle at @70°C. Normal windows usage will bounce the temps from @32°C to @55°C just opening an app or game, so setting the fan curve over that limit stops the ramping until necessary heat limits go beyond, such as in heavy gaming.

Too many ppl place too much significance on temps below 70°C, when honestly there's exactly none. A cpu at 45°C is exactly the same as a cpu at 65°C. As long as working temps are maintained under @70°C, you are golden. So running the fan slower and a temp of 55°C gaming isn't an excuse to ramp up the fan to get another 5° cooler cpu. It simply doesn't matter.

And yes, the stock fan on most coolers is pretty miserable, vendors are constrained by usage of existing company products. CoolerMaster doesn't make a superior fan, so the hyper212 is stuck with the best CM has. Coolers made by Phanteks, Noctua, Cryorig etc having a serious advantage there.
