I have the 8900 for a few years and I often leave it on even when I’m away from the computer for hours. I have it set to go to sleep after a period of time but with certain programs open it won’t do that automatically so it stays on.
Hope you can get your problem solved.

105F doesn’t sound so bad. It’s going to be 117F here in Phoenix today. Now if you are talking 105C, you better get some help. Your CPU will start to throttle down at that temp.

105 deg F (40.5 deg C) is warm, but acceptable. 50 deg C (122F) is absolute max for longevity in my opinion. For example WD specs their drive’s operating temp range from 5-55 deg C or 0-60 deg C, depending on the model, but cooler is always better.

This Baby Dell has been running for a few hours with the front and side off, and it went to 105 when I was making it work. Now it's 102 - 104, which a lot cooler than when the front and side were on it.

We have a computer that is in the basement - cool but dusty.
It started failing once.
When I opened the case, the CPU fan wouldn't turn because it was so buried in dust.
These machines have to be kept cool - and under normal conditions they do.

You can make a shroud to hold a larger diameter fan over a smaller hole. A little bit of sheet aluminium metal and maybe a few spacers. Front and back. In the event of a warranty return they can be taken off. Lengthen the fan leads to suit. There should be (although they may not) a couple of fan outlets on the motherboard that you can use. Man is an ingenious beast when necessary. Be careful if using a single fan outlet to drive multiple fans as there may be a setting in BIOS that is monitoring the fans speed. The fan pins are usually 3-4 pins with a couple of them for power but the other lead is a speed or rpm monitor. So just use the power pins only.
The Western Digital Blue drives are WD's lower cost drives and not the best. My experience is about a 20-50% failure rate in the first 5 years. You can usually tell a drives longevity by checking the model numbers and seeing what the usual warranty period is. WD blues are 3 years but WDs black drives are 5 years.
Also check any fans you purchase are ball race rather than sleeve bearings. And hopefully have 2 bearings rather than a single one. This has nothing to do with longevity (well it does but this isn't the primary reason) but sleeve bearings eventually seize by sucking air and dust through the sleeve. A ballrace usually (but not ALWAYS) does the same but keeps running although they will get noisy. When you hear it rattle it tells you to replace it.

Multi-tasked fan - I repurposed one and made a negative drier for 35mm film. Built a shallow wooden box. I mounted the fan on one end for input. Mounted a length of plastic pipe on the other end (like a white chimney) with a grid on the bottom where the film carrier would rest.

Tapped the film carrier to knock off the larger drops, dropped it in the pipe (had room for 1/2 dozen film carriers, rarely had more than one or two), turned on the fan, & voila, nicely dried negatives in about 1/2 hour.
