I'm starting to feel interested again in building my own system.
I used to do it all the time, back in the 90's

But at work I use the big metal they supply (or big VM), so there's no use for power and to spend $$
I simply get a really good laptop from a good vendor...lasts for a few years.

But now that I've got time, mind and moolah with the remote surge and IT gig resource shortage.
I'm thinking of doing a Frankenstein again...just for the hell of it.

I used to be a SME on HW specs back in the 90's...guess I gotta get back into it.
Figure out all the nooks & crannies to get the biggest bang for buck.

And I don't need to do the ultimate gamer system, I don't do those types of games.  (Civ is my cup of tea)
And I don't need ultra power either, hell I got access to Supercomputers (and even Quantum prototypes, no BS)
This is just for shiats and giggles.
And have an alternative whenever my laptop is being a PITA (it's not if, it's WHEN for any system)

Hmm...where to start, well obviously an AMD chip (which I've been a supporter for since the early 90's and their 486)
And fans are MUCH more important now, then in my elder years days "way back when..." ;)

We'll see...

I am by no means an expert, but this site was a huge help when I decided to jump in. I started with one of their recommended builds, and then swapped out a few pieces (based on availability, this was Fall 2020) which it also helped with.

Power draw has gone through the roof with the newest generation of CPUs and GPUs, with commensurate heat generation. 1000W PSUs are back in style.

Hardware RAID is dead, Crossfire/Dual GPU setups are dead too. The newest AMD CPUs went to LGA, Intel did that a few generations ago, so you don't need to worry about bending a pin on a CPU anymore (You can still bend pins on the motherboards though).

I'm sure there is more that I'm forgetting, but you'll figure it out. It's really never been easier to build a PC, everything is poke-yoked to prevent mis-slotting, so you can't put anything in backwards anymore.

Another vote for PC Parts Picker. I had to buy a built MSI this time because I needed a box right now at the wrong time but if I was building from parts I'd start here.

Of course, all this advice doesn't mean shiat when you're building an oddly-sized SFF. I've got three fans, all set to exhaust, plus the GPU cooling system. One of the fans is a standalone right next to the PSU blowing out, and is the only one set up as a case fan. Another is attached to the CPU heat sink with paper-clips and tied in to the CPU fan logic, and then there's the actual CPU fan on the other side of the heat sink.

It's... more or less good enough, but I am getting a 13-15% hit on Cinnebench scores because of it, and run an aggressive undervolt to keep idle temps in the 40s with a super-quiet fan profile.

Buy the biggest fans you can. They spin slower (and quieter) and still move air. Easier to do if you use a full tower case.
 
2022-09-29 12:32:33 PM  
One note that came to mind, FTFA:

Pull:A pull configuration reverses the fan position to suck air through the fin-stack. It is not as common and generally not as effective as push-oriented fans. The same principles about positioning and expelling warm air apply here.

That's about installing an AIO with a pull configuration, so it's pulling cool air from outside through the radiator and in to the case. I'm not sure that's true that it's generally not as effective. IIRC Corsair was recommending folks set them up like that, as it means your radiator is getting the coolest air from outside, rather than air already heated by other components, such as your GPU. And I believe it does actually result in slightly lower CPU temps.

Pretty sure that's the stock intel fan from Intel's Pressler architecture.

PCPartspicker is a great website.  If you can come up with a budget, there's more than a few farkers (myself included) that can probably get you a pretty descent layout.

If you have questions on anything, you can always post them to a site like LTTforums and get some more expert advice on certain components.

Hardware has changed a LOT in the last decade, but the plus side is that over the next year we'll have more solid options than we've ever really had before.

Don't even both with high airflow cases unless you get a deal and don't mind some cardboard. Without something to guide the airflow anything your fans are pushing are just going out the holes instead of where it needs to go. It's just a dumb marketing gimmick to sell more fans.

Case pressure doesn't matter all that much as far as cooling goes, but it's nice to have because it tends to blow dust out. Mounting a radiator on the exhaust helps a lot for this since it increases backpressure.

Also, don't worry about maxing out CPU cooling, for best efficiency silicon needs to be around 65-75 Celsius. Shoot for that as the top end at max load and adjust your fan profiles accordingly for the low end.

Make sure the new fan's plug has the same number of pins as the socket. Those little wires are difficult to solder.

A 3 pin fan will connect to a 4 pin header and a 4-pin header will work with a 3 pin fan.  Done it tons of times. You just lose the ability to control the fan rpm if it's not a 4 pin fan on a 4 pin header.

Ugh. A 4 pin fan will work on a 3 pin header as well.

Ever since 3d graphics cards came out, I've tried to set up a little negative pressure in the case (maybe one fan or slight config difference to achieve this).  Many newer cases and vented to hell and back so really, you could have all fans pointing out (or probably in) if you wanted and not have issues.

I would add to watch a vid on installing in an M2 slot - I depends on the MB and *should* be an easy installation but it would suck to not seat it and crack a $200 hard drive the size of a credit card.

Depends on the motherboard.  Most motherboards these days only support varying the fan speed using PWM over pin 4, but some still support the older method of varying the voltage over pin 2.  There are also adapters that allow a 3-pin fan to work with a 4-pin PWM-only header.

Anadtech is another great site, just like Tom's. Those two are very old and very trustworthy sites.


The article was good. case cooling is an afterthought for most builders but it is important.

FTA: "Usually, the pretty brand sticker is also on the intake side, since it's more likely to be visible through glass or mesh side panels."

That has not been my experience at all. Every computer case fan I can recall using had the label on the exhaust side (i.e. blew the air towards the side with the label).

I usually look at the spokes for the fan's hub. For computer fans the air is usually being drawn in through the open side, and expelled out through the side with the spokes supporting the fan's motor.
