I like the idea but if it means a complete break from everything we're currently doing, buying the entire stack from an unknown company, it's a daunting change.

DrDork posted:Yeah, but gyroscopic precession only works when you're applying a force perpendicular to the plane of rotation. With the way the disks are loaded in that new chassis, the force of sliding the bay in/out of the rack should be almost entirely parallel with the plane of rotation, so the force simply gets applied directly against the spindle, which should be more than capable of handling it. And the spinning disk should act as a stabilizing factor, anyhow.

Well, my desire for a silent HTPC/NAS in the living room came back to bite me in the rear end. I have an ITX motherboard with a passively-cooled Celeron J4105 in a Fractal Node 304, with a 140mm fan in the back and two 92mm fans in front. All three fans run temperature controlled by the MB (CPU temp for rear fan, MB temp for the front fans), with a target temp of 45C and the lowest fan speed. This does work pretty well, since the CPU idles at around 35C with barely any airflow, so the fans basically just idle a gentle and very quiet stream of air through the case, keeping the disks around 30C as well. The disks are the loudest part of the build, and they're barely audible even close up, aside from the old Samsung 1TB that I threw in there just because I had it. Dumbass me didn't even think to consider the PCIe SATA card and whether that was getting enough air blown across it, when pushing a lot of I/O. At least not until my NFS shares were suddenly read-only and dmesg showed a bunch of btrfs checksum errors  At first I thought I was losing a disk, but SMART showed nothing and the heatsink on the SATA card was toasty, to say the least. Apparently those Marvell chips do get quite hot under heavy load. I cleaned up the cable management in the case and cut off the extra CPU and PCIe power cables from the PSU, since they were just getting in the way of the airflow, there really isn't much room in there with a full complement of disks. I had a spare heatsink from a Raspberry Pi project, so I stuck that on the back of the SATA card behind the controller chip, I figure that should help a bit. Right now it's running fine with that done and the fans on a medium speed, but a bit of active cooling for the SATA card seems sorely needed. Keep those temperatures under close watch!

I have a tiny rear end fan bolted onto the passive heat sink of my sata card. I’ve posted it in this thread somewhere. Helps keep it pretty cool.

Yeah, I'm either going to strap a spare fan in front of it, or buy a Raspberry Pi heatsink+fan on eBay. There isn't really any good way to screw a small fan directly to it.

It's a very tiny heatsink, about 25x15mm, and the smallest fan I have is a 30mm, so I could get one corner screwed in. Maybe if I loop a couple of thin zipties around the board in front of the PCIe connector, that could hold the fan.  I've got an 80mm fan and I found a cheap PCI slot bracket to hold it, probably designed for graphics cards. An 80mm fan is obviously ridiculous overkill, but if it works, it works.

That's certainly a possibility, I have plenty of spare brackets of all kinds. The current plan is to ditch the 80mm fan idea, and go with a 40mm Noctua fan and zip-ties, around the board in front of the PCIe connector and right between the two small electrolytics. As long as I get some air movement over that heatsink, it should be fine.

Gonna Send It posted:And ridiculously quiet for their size! They don't move much air, which I found out the hard way trying to replace all the fans on my 3D printers with Noctuas to cut noise  But literally any airflow will be enough to cool that chip so I'd use it for this in a heartbeat.

As long as it's better than the little 30mm 5V fan from my Raspberry Pi project, that thing has a really annoying mosquito-like whine, while not actually moving very much air. Running it at 3.3V is a bit better, but where do you find 3.3V easily in a modern PC? A spare SATA connector, I guess? KozmoNaut fucked around with this message at 08:41 on Jun 2, 2021 |

I can't hear it inside the case (Fractal Define R5) over drive noise and 3x 140mm fans.

Expansion cards, they have all their components on the underside in an upright PC case, which is less than ideal from a cooling perspective, especially for passively-cooled cards. I think the last cards that were right side up were ISA cards?

The atx standard in general sucks, video cards use more power than cpus now but have to fit in a space 1” high with the hot parts facing down and bad airflow. You should be able to put a tower cooler on a video card.

I remember BTX and what a wet fart that turned out to be, and it did have the side flipped so expansion cards faced up iirc. It was pretty forward thinking with actual emphasis on airflow and cooling and the fans blowing over the passive heatsink cpus instead of fans on top etc.

What's great is Dell towers do it right, and it wouldn't even break anything to just mount everything upside down but noooo way we can mirror the standoffs! I'm sure a bunch of neckbeards would be upset but I can't think of why.

They clearly should've realized that over a quarter century later, devices would be pulling more power through daughterboard(s) than the entire system used back then, and that the PSU wouldn't be the only fan in the entire case.

You've saved me an enormous amount of headache. Poked the heatsinks yesterday, and yep, they're super fuckin' hot. Thank you!

I hope it stops giving errors once the temperature gets under control again  I always try to get the beefiest coolers I can reasonably fit, with the largest possible fans. After all, if it can cool a 250W TDP CPU at full tilt, it can cool a 100W TDP CPU at lazy mode speeds and be very quiet. I have a completely overkill Scythe cooler on my Phenom II, and at normal loads the 120mm PWM fan spins so slowly, you can easily count the revolutions. Before that, I had one of those gigantic Zalman flower coolers on my Pentium 4 and a very large double-sided passive cooler for my Geforce 4 (with a large fan at 7V suspended in front of it), for the same reasons. Never skimp on cooling. It didn't cross my mind that SATA controllers would get that hot, until I burned my finger

Sure, there's a reason the RPi4 has a heatsink for the memory. But I never really thought about the load that eight SATA devices would put on a controller at full tilt.
