More a personal rant than anything.....
In contemplating building a new computer to accommodate future Linux Ubuntu-based distros the thermodynamic concerns are becoming ever more frustrating. Mostly because I've always contemplated noise factors before heat factors. But the 12th and 13th generation Intel cpus are making it all very hard.
I've pretty much settled on the i5 12600K cpu as a compromise of sorts, given it's base power of 65 watts on the low end and 117 watts for turbo power. I good compromise given I don't intend to use it as a gaming platform where my present use all day long remains primarily between 29 and 39 degrees celcius.
The real challenge now is that both the computer cases I have presently were from an earlier era in computing, about 12 years ago. My older case is a Cooler Master CMP-350, and my present case that houses this computer is the rather unique Silverstone TJ08-E.
I was going to simply put all the guts of the Silverstone case (except for the GPU) back into the Cooler Master case, which worked fine with all those old specs to consider. The problem remains that putting current components into the Silverstone case, which has limited cooling possibilities. The big plus of the case a dozen years ago was that it created positive airflow via a frontal 180mm fan into a very small main part of the case housing the motherboard with a 120mm exhaust fan at the rear of the case. Despite the small dimensions of the case, it presently has the old reliable and large Cooler Master Hyper 212 cpu cooler/heatsink.
Those more recent 12th,13th and 14th generation cpus run considerably hotter when pushed to their limit. That at the moment my i5-3570k cpu runs great in that little Silverstone box. However transitioning from an i5-3570k to an i5-12600k inherently involves some very different thermodynamics. And as it stands, I wanted to reduce the size of the 180mm frontal fan to a PWM 140mm fan that is easier to clean and offers more pragmatic speed control than the 180mm fan that only has a switch for a noisy 1400rpm to tolerable 700rpm.
That real problem? I don't realistically see two such fans as being sufficient to cool this case with a current cpu's heat concerns. At least not on the high end of 117 watts of power. Despite a theoretical ability to maintain positive airflow in a very small space. Even while still running an older Nvidia GTX1660Ti gpu that takes less power compared to the 3 & 4 series Nividia gpus.
Sadly I think
@Outdated is right. I'm gonna have to give up my Silverstone case for bigger one that can handle at least three 120/140mm frontal fans against one or two 120mm exhaust fans to maintain positive airflow involving much higher temperatures at peak usage. And no, I'm not interested in an AIO.
The big frustration at the moment is that I'm not impressed with all the cases on the market for a variety of reasons, particularly that most are missing a 3.5 and 5.25 external drive bays. Something both my two cases have, from a different era. One to house my removable SSDs and the other to house an obsolete DVD player.
There are a couple case out there, but are either too damn big or not very well designed IMO.
In as much as I want to proceed and rebuild my Silverstone TJ08-E case with current components, I'm becoming ever more spooked about the potential thermodynamics. Ugh...building a new system has never been so tough. Too bad I fell in love with this case a long time ago...
Too bad Ubuntu is contemplating a cutoff date of older cpus, mirroring Microsoft over Windows 11. Now forcing me to upgrade my hardware in the next three years...but then with developers they're always thinking of building that better mousetrap. It's not guaranteed that Ubuntu will come to such a decision, but if I have to bet on it I suspect it will happen, and along with Ubuntu other distros will follow suit.
I may just say, "Damn the torpedoes full speed ahead!" and put new guts in this old Silverstone case. I love it so much...though can a big, strong intake fan and a weak exhaust fan alone produce positive airflow sufficient to cool an Intel i5-12600k cpu occasionally running at 117 watts?
(I know the demands of a 3 series Nvidia gpu would put the heat demands over the top, but as a non-gamer I plan to continue using my GTX 1660Ti gpu, given the backwards compatibility of gen 5 PCIe. It's also no accident that I want to use such a gpu that is no longer than 8 inches inside a smaller case!
Most of all, if I'm still around in another three years, I want that hardware option to stick with Linux rather than to be forced back into the evil empire of Microsoft. Then again I could die and end this dilemma having used a marvelous version of Linux Mint. Problem solved!
