Oh, goodness, thanks for bringing up those painful memories. Of course, nowadays it's still not completely smooth--I still have to reboot the cable modem if I switch out the router.

I have a pair of 4GB DDR3 sticks, if that'd be sufficient.

Yes, it does, and for an extra few bucks (because it'll take a bigger box), I can include the PSU that came with the computer. These parts are from the wonderful times when all the big PC manufacturers used standardized parts!

Fair enough. I have a CPU/Mobo/RAM combo up for grabs. It's a working pull from an old HP tower (I wanted the case). i3-3240, 8GB RAM, rear I/O plate included. $15 shipped

Any chance you could clean up that area with a q-tip dipped in alcohol and post another pic? How big are those traces? I could make an attempt at repairing those--I do a fair amount of smallish SMD soldering at work, so I might stand a chance.

Yes, standard ATX power

I have a Dell Optiplex 790 motherboard with an i3-2105 and 6GB of RAM that I'm trying to get rid of. Anyone want it for the price of shipping? The front panel and fan headers are non-standard, but I'll include adapters for them. EDIT: Claimed!

Fortunately, the games played most in our house are Starcraft 2, Minecraft, TF2, and Kerbal Space Program, so I haven't been suffering terribly. Amazingly, the Windows 7 installation on that computer is probably 7-8 years old by now.

Man, I've fallen behind the times--my rig at home is running an i5-3570. Next year, though, I'll finally get around to building a new one!

LOL I just decommissioned our old HTPC, and all it has is a i3-2105, so I'm not much help, sorry :D

I totally get the reason for the plastic. I just think it's silly that the industry has standardized on something that is mostly useless.

The case is amenable to that idea--it has a pair of 80mm intake fans, and I can blank off other areas to steer airflow where I need it. I took a closer look at the 120mm intake fan on the current PSU, and was a bit annoyed to find that over 50% of it is blocked by a plastic sheet, so that the...

I suppose I could stick a server PSU in there, but the chassis is designed for an ATX PSU.

The title just about says it. I need a PSU that has an 80mm fan in the front or the back, like in ye olden days, rather than on the large side. It's going in a 2U chassis, and I don't know yet whether it'll have space on top for an intake, so I'm trying to moot that question entirely. The...

Are you sure the windings are burned out, or could it be a thermal fuse blowing? I ask, because I've repaired multiple fans with burned thermal fuses, it's a fairly straightforward repair (and you can replace the one-shot fuse with a resettable fuse), and you are clearly somewhat handy...

Yup, I recently bought a couple of spare 10mm sockets, too, because sometimes you need one on the manual ratchet and one on the cordless one, and they always go missing at the most inconvenient times. And yes, I've lost a few down engine bays.

Well, this *is* the perpetual FREEBIE thread...

A question on the Dell Desktop 3010--are you selling it with a monitor? I'm a bit confused since the 3010 is a desktop and your photos also include a dell laptop.

What model are the thin clients? I'm using a Thin Client (Dell Wyze Dx0Q) as a file server, and with the right wires, it can accept a standard 2.5" drive. https://www.parkytowers.me.uk/thin/wyse/d/dx0q/apps.shtml

Just posting here as well--I paid for a key, and got two bad keys in a row. No communication from the seller since March 1, despite a couple of follow-up messages.

Aw rats, I just ordered one of those off ebay....

Don't feel so bad--I'm still rocking an i5 3570!

Heh, what are the odds--I have one sitting right here on my desk. PM me your shipping info. Probably $3 for shipping

I've taken apart a fair number of LED light bulbs, and I'm an EE, so I can do at least a little bit of analysis. tl;dr: Go ahead and plug it in to 110V. You won't do any harm to it. Longer version: You've got 24 LEDs in series, which would come out to about 75-90V. That can be done with a...

YGPM on the SSDs

I don't see a price. How much are you asking?

That's actually normal--many fans won't start at 6V, but if they're already spinning, they'll happily keep spinning on 6V.

So the blue line is basically sitting at 0, at least when the multimeter is sampling it. And 6V on the red line is about half what I would expect. There's something sort of unusual going on here.

ryan's right that it's important where the green wire goes--because there's current passing through the resistor, the voltage at the two ends won't be the same. In your photo, it appears that you're using the multimeter wrong--the black probe isn't contacting anything. You need to put the...

It looks to me like the green wire is connected to the wrong pin on the left side. It looks like it's connected to pin 3 when it should be connected to pin 2.

From the datasheet, it almost looks like the fan treats that third line differently from how a "normal" fan does. I may be misinterpreting the datasheet, but it kind of looks like the fan holds that line low as long as the fan is spinning, rather than outputting a square wave to indicate its...

Oh my goodness, you're right! usafltg - you'll want to check out the updated version of my post above. Apologies for the mistake!

correct--the fixed resistor would take the place of the potentiometer

The LM555 you can pick from this list: https://www.mouser.com/Semiconductors/Clock-Timer-ICs/Timers-Support-Products/_/N-4k3ax?P=1z0z63x&Keyword=555&FS=True (they all work the same) EDIT: A previous version of this post had bad math. This should be better: For 9000 RPM, you'll need a signal...

So DDR3 is old enough to show up in this thread? yeesh, I could use some more...

I have a 2GB DDR2 stick out of a Dell 745 or 755 or 760 or something. PM if interested. $3 for shipping.

I have one! Shipping will cost about $3. PM me if you want it.

I dunno about you, but there are a lot of very nice laptops in the consumer space. Dell, HP, and Lenovo have some rather pretty (and well-made) laptops if you're willing to spend more than $600. Where do you live where people are giving away 2-year-old desktops? Because I could use one--I'm...

Do we have any benchmarks showing the cumulative performance impact of all the mitigations?

PM sent.
