the reflection in her eyes:
I sadly don't know enough about active to know what to give. :'(Who would be interested in participating in the AAMML holiday gift exchange this year? : D
Everyone will have a list of favorite anime they like and/or gift ideas. : )I sadly don't know enough about active to know what to give. :'(
Body pillows for everyone?

Picked up a couple of old workstations over the weekend, 245 dollarydoos each or approx 180 freedom units.
Dell T3600 (Sandy Bridge E)
E5-1620 (4C/8T @ 3.7GHz)
32GB DDR3 ECC 1600MHz, this platform was quad channel, pretty decent even by today's standards
240GB SSD (some liteon, not too terrible...for 2013)
Quadro 2000 (pretty bad but ehh good to have around for troubleshooting)
Win 7 Pro wooooo.
Certainly gives my old 3770k rig a run for its money, I still only have 8 gigs of RAM....
Hmmm wonder if I should buy the e5-2687W for $150, 8C/16T, 3.1GHz base, 3.8GHz turbo. Ehhh pushing $400 per computer is getting a bit pricey, I think it's unnecessary if the main purpose is 1080p 60fps gaming with something like a cheap 570 class card.
For 11.11 day, which is basically China's 'Black Friday' sales, I ordered a few new additions to the crew. Priestess from Goblin Slayer and Rikka from SSSS Gridman (I haven't seen enough of the show yet to like her, it's just that as a staunch follower of thighdeology, I have to pay respects to our queen)..
What are all those workstations for, out of curiosity?
I have a weekly LAN party so we always need at least 4 systems. One of our original sandy bridge builds is starting to go, and getting a replacement motherboard is surprisingly expensive! I might replace my main system with one of them, or maybe upgrade the Z820 workstation after I repair it. (ambient temp sensor is dodgy so the fans spin at 100% all the time)
Yeah it's gotten to the point where we needed some redundancy, so that's why we have a spare system or two lying around in case of component failure. It all sounds hardcore but our current systems are just hand-me-downs, because building new systems just for one-day a week use is waaay too wasteful.
Still, I'm blown away by the value of old workstations, and it's becoming a bit of a hobby to hunt for good deals on used hardware.
my latest fan issue was "solved" with a bios update. of course I tried pretty much everything else before that because I'm a moron. the fan on the GPU was starting at boot, would stop after a sec and start again after maybe 5secs but by then it was too late and the motherboard was telling me to evacuate women and children first. as it was a new fan, of course I assumed that it was bad in some way(something to do with detecting the voltage when turning or whatever actual method to confirm the rotation speed). I wasted a good afternoon on that.
The HP Z820 uses an NPN transistor's base emitter diode junction to sense the ambient temperature, when it fails the system fans go full awoo on start-up and can't be overwritten even with the BIOS idle speed control. The transistor (2N3904 in this case) is located on the front panel power button + speaker assembly, it's under some heatshrink on the speaker connector end. I think any jelly bean NPN transistor will do but I replaced mine with an MPSW42 I had on hand because in my sick twisted mind, a 1W 300V transistor will be more robust, who knows.
Computer is nice and quiet now, apparently this is a very common issue. go figure. Hrmmm I wonder if it's worth Noctua'ing this baby up, there is a lot of "bearing noise" even when the fans are slow. Maybe a drop of oil will help...

of course it did nothing for my original reason to try and change the fan. because that would mean I actually did something meaningful, and we just can't have that in here ^_^. I get a low freq modulation of the fan noise(somewhere between 1 and 2hz), it's not a loud fan noise to begin with but somehow the modulation pisses me off more than the fan noise itself.
I thought it would be some structural stuff on the PC or the fan creating a resonance and shaking the fan at that freq, but I've noticed that my fridge has that same slow modulation when the compressor turns on, and the other night I also heard it in the noise of a washing machine down my street when passing in front of their window. so now I'm wondering if I'm going full Jim Carrey in "the number 23", or if that weird fluctuation might be in the electrical grid? which is antiquated and unstable anyway, whether I'm right about this or not.
