Before doing any apps (games, stressing) make sure you have a clean, updated and activated Windows install. Check all your hardware in settings and update drivers. Give it a few reboots let us know what the hardware is telling you.
So you have four 4x4 case fans, two CPU cooler fans, and two GPU fans. Sounds like it could be loud, especially if the case fans are mid-tier or aging. Is the water cooler pump contributing at all?
Yeah almost impossible as baby's will go in through the smallest of openings (even netting) and get fat with organic dust debris and lay eggs, etc. Just get a big old case, put a roach motel inside and change out every couple weeks.
Of course depends on CPU and cooler, but in general for example consider the review for Arctic’s Liquid Freezer III. In this review the cooler can keep a 14700k under 80 under stress. This is impressive and the cooler would probably keep your CPU even cooler. However, spikes upon load are...
If you push your CPU to 100% then it will spike 80+. Not much you can do to stop it. I guess the bigger question is does the temp plateau or sink once all your fans and throttling kick in. If the temp keeps rising then you have a problem. But I am not an advocate of stress testing. Might as well...
For now you could buy a matching nut and screw of appropriate length and diameter to go through the bracket. The nut can sit on the top and you can hold it in place with pliers while you put the screw through. Just make sure you torque enough.
Do you have the V2 version of CPU cooler? This is a strange product given the reverse fan and it may be giving problems with the air flow you have designed. Either way, both versions are at the bottom for watts cooled on Tom's chart. You may want to invest in a better cooler. Front to back...
You kind of came and crapped on his thread over a topic for which there is no argument. Based on a very quick analysis on the internet, it seems your talking apples and oranges. I can quickly find the merits of a DSLR over mirrorless and vice versa. So why would you have to come into the thread...
What you need to establish is if it works before you install non-essential programs. After you install Windows, check your settings to make sure all of your hardware is detected and the most updated drivers are installed. Update Windows in the settings and make sure everything in the BIOS is...
Usually not good to obstruct intake side of fan. That is what you will be doing and especially once that first heat sink starts accumulating dust. It's going to be a real chokepoint. Try it out but monitor your temps.
