Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I've seen in this thread:

Fewer Letters More Letters
PCIe Peripheral Component Interconnect Express
SATA Serial AT Attachment interface for mass storage
SSD Solid State Drive mass storage

3 acronyms in this thread; the most compressed thread commented on today has 13 acronyms.

Gotta love a good TLA.

When I was a kid, the first PC I built was a white box with a Pentium 4 HT, which was still a fairly new CPU at the time. It ran hot so I cut a hole in the side of the case, bolted a 120 MM fan in the hole, and covered it with a shroud that I think I must have fabricated with Aluminum facia.

It didn't look pretty but it worked. And it kept my bedroom toasty in the winter.

I mean, that's essentially how my first tower PC was cooled. Bought it as a complete PC and the cooling was a blower style fan that sucked cool air through vents on the side via a plastic shroud.

And it was also one of the wonderful pentium 4 space heaters with incidental compute.

Zipties and brown for life.

[–] [email protected] 6 points 2 years ago (1 children)

Gotta give it to noctua for making brown cool

[–] [email protected] 7 points 2 years ago (1 children)

I'd say it was the fan that solved the overheating problem, not the zip ties.

[–] [email protected] 7 points 2 years ago

I tried just the fan on it's own, but gravity always left it sat at the bottem of my case.

[–] [email protected] 7 points 2 years ago* (last edited 2 years ago) (1 children)

Nice, I ended up just taping a fan on underneath using HVAC tape applied directly to the heatsink.

The plastic screw thing that holds the heatsink on can become brittle and break after some years. It might be worth picking up some small nylon bolts online before that happens.

Edit: or I guess zip ties would work if it comes to that....

[–] [email protected] 2 points 2 years ago

I placed my fan over the heatsink and did an X pattern in zipties to hold it all in place

Yeah, sadly a lot of server hardware is designed for high air-flow rack-mounted cases and doesn't deal so well with normal ventilation somewhat optimized to reduce noise. Especially PCIe ethernet cards seem to get really hot, but SATA extension cards are also problematic. Adding some better passive cooling also often helps.

If I could find a internal server fan smaller then 20x20mm. I'd stick one next to my 1U CPU Cooler. But for some reason I can't find one. Needs to be smaller then 20x20 because it would sit on top of the motherboard in a closed 1U server rack frame.

[–] [email protected] 1 points 2 years ago (1 children)

You can use a larger fan and a shroud to redirect the air flow, similar to how laptops are cooled.

[–] [email protected] 1 points 2 years ago (1 children)

I'd like to keep the cooling internal, I just have it sitting on a shelve next too other desktops k3s nodes.

[–] [email protected] 1 points 2 years ago (1 children)

I just meant you can have an internal fan that's larger than your heatsink, and a shroud to direct the airflow to it. It requires less vertical space, but more horizontal space.

[–] [email protected] 1 points 2 years ago

Oh yeah that makes sense, the board does come with a shroud, my fans just don't have the power to push air through it well.

[–] [email protected] 1 points 2 years ago (1 children)

There are centrifugal fans that are quite flat but they intake airflow from a different axis they exhaust it from. Could still work

[–] [email protected] 1 points 2 years ago

Hmm I've gotta look into that, It's Dell Poweredge R410 Server: looks like this: https://i.ebayimg.com/images/g/er4AAOSwNDVfyTuN/s-l1600.jpg.

It would need to fit inbetween two heat sinks pretty snug.

The board doesn't come with any extra on it. There is one used but it doesn't boot without that card. Not really sure what it does. It's a Dell Poweredge R410 Server: looks like this: https://i.ebayimg.com/images/g/er4AAOSwNDVfyTuN/s-l1600.jpg

Do you mean the card with the SODIMM next to the CPU? that is a raid card, and it looks like it is responsible for the front drive bays.

[–] [email protected] 2 points 2 years ago

Oh yeah it def had the SAS Backplane wires, I'd switched to using the SATA on board since it doesn't have the same HD capacity limits. I think it was a max of 2tb with the backplane and I'm using a couple of 10tbs. Maybe their is some weird bios that requires it to be on board?

Using consumer hardware as a server.

What's that CPU cooler? I've been looking for super low profile coolers.

[–] [email protected] 2 points 2 years ago

Its the stock CPU cooler that comes with the newer Intel's (this is a 12th gen i3)

"Recycling brackets", 1000 pcs bag.

This bag contains already used zip ties in various lengths and colours. You can reuse the items and be creative. Build modern art for your living room, a fan holding bracket for your server or a cool handle for your hot coffee cup.

Tag this as NSFW!!!

[–] [email protected] 1 points 2 years ago

I did this without the zip ties, kind of wedge it between the motherboard and the power cables.

[–] [email protected] 1 points 2 years ago (1 children)

I just screwed a tiny Noctua right into the heatsink of my LSI. Worked great.

(The screw holes lined up with the gaps)

[–] [email protected] 2 points 2 years ago (1 children)

Always, if it's not, you need more zip ties.
