Orac Lives

Back on December 18th, Orac went down unexpectedly....it was shortly after I turned on the heat that morning. So, at first I thought it was a heat problem. I directed fans at it, dropped in a slot cooler, scaled back BOINC (eventually suspended it). But, Orac would suddenly stop. I watched thermal monitoring in cacti, and it CPU temps weren't hugely different than before. After a while, I had to go to work...so I left it off while I mulled options.

I tried changing the rear case cooler (when I had it open to add a slot cooler and check the other fans), I had bought a 92mm fan with the plan to replace that...but I discovered that I had bought the wrong kind. Probably could've made it work, but opted to try again. I don't recall if I ever checked if the CPU fan was okay. Last time I had cleared out a lot of dust from it....it wasn't full of dust this time, is all I recall.

After some more fiddling I started to suspect power supply, I had been thinking of getting a bigger power supply for it for a while...so I went ahead and got one, a Corsair Builder Series CX V2 500-Watt 80 Plus Certified Power Supply - CMPSU-500CXV2, along with different 92mm fan (a Zalman ZM-F2Plus 92mm Silent Fan). Mulling things some more and reading other online articles...I then added some more items to my order, like new thermal compound and a CPU cooler -- a Thermaltake TR2 M21 RX A4021 CPU Cooler for the Intel Processor 115W LGA775-Prescott -- which later turned out to be the wrong kind....need a 4 pin fan for CPU. Though wasn't convinced I needed a new cooler.... But, the stock cooler was rated for 95W, and Intel's website says my CPU does 105W.

Even though I got the new power supply on 22nd, and I took the 23rd off from work...I didn't get around to actually working on it until late on the 24th (after it was too late to get anything one-day Prim for the 27th.) It was quite an ordeal getting the power supply in...had to pop the fan off the CPU heat sink to get access to all the connectors and stuff. Put the fan back on too soon, so had to get it off a second time. This time it broke. Well, I guess I swap the cooler after all. Except then I discover that the new cooler I had gotten was the wrong kind. So, I go to Amazon to see if I can quickly get a different one. No luck there....so order one by regular 2-day Prime. I went with a Arctic Cooling Freezer 7 Pro Rev.2 - 92 mm - 130W.

Original fan and the previous one I ordered, were the kind that blow to the CPU. This one has heat pipes and blows across. Reading reviews, I saw warnings about how much taller these things are and whether it would fit...so I decided that 92mm something was probably the safe maximum to consider. After narrowing through the choices via Amazon Prime...it came down to the one I got or the Arctic Cooling Freezer 13 Cooling - 200W. Since, I had about 72 hours to place the order...I held off, to see if there was anything else I wanted to add before ordering. Mistake. Later on Christmas day, the prices on lots of things...specifically these CPU coolers went up. And, the 13 went out of stock (by Prime.) Though I had decided the 7 was the more likely choice, since I didn't know which way I should position the cooler and it had four way flexibility. Though I suppose others would have the flexibility too...its been so long since I've done this kind of thing...I don't know.

Anyways...I finished putting orac back together with its new power supply, moved the slot cooler to the bottom. Removed the old heat sink/cooler (should've kept the parts though) and cleaned off the CPU. And, set Orac aside for later work.

Getting dry in my condo, cooler too.

Winter has been weird this year...but there's a winter storm alert finally? Though its the rain and snow kind with ice accumulation and inches of snow type. Just as long as it isn't another icepocalyse of 4 years ago.

Though seems interesting that the computer I bought to replace the one I lost during the icepocalyse, died on Friday. Almost as if it was designed to die after 4 years. Annoyed, because its orac, my backuppc/file server. There's 16 drives on the machine, a total raw storage of 23TB....though only about 11.5 usable TB. And, a whole lot less in TiBs.

I'm hoping its something simple though....was looking at the hardware monitor in the BIOS screen...where it reads out voltages...and the lower voltages are low....though are those from the supply or are those generated on the motherboard? Seemed to me that motherboard generates some of the values, but not sure what I'll do if that's the case.

Also seems odd that it died shortly after I turned on heat Friday morning. Anyways...I had been considering getting a new power supply for orac for other reasons, so I jumped over to Amazon and took the plunge to get a new one by Amazon Prime. I had also been meaning to upgrade the case fan on it orac....I mentioned this before....stock fan is 80mm, but there's holes for a bigger fan. I had/have some extra ones around, so I had tried those...except that my extras are too big...so not 120mm. So, I had looked at 92mm, and I did end up with one, but failed to notice that it wasn't a 3-pin fan. So, maybe I'll add one of those to.

So, cart is adding up...and I'm looking at items I have 'saved for later'....and well, new humidifier is among there. Its pretty expensive....~$88 Its an Essick Air Tower Humidifier, though its about the same price as what my old Essick Air unit...though thinking the tower form would work better with where I've been using the old one, plus the old one's fan has become the issue... Though I guess its only 2 years old. I wish I could find something like the humidifier I had back when I was in Medicine Hat....while it eventually got nasty inside, that thing worked well for years and wasn't that expensive as I recall. And, it was easy to fill too. Since, then...I guess the Essick Air is the first one that I got more than one season out of....two whole ones, in fact (though some debate as to how well near the end.) And, it did a good job too. Plus the tower I'm looking at, uses the same wicks as the old one...so I already have an extra set somewhere.

Though having an extra set of wicks isn't a requirement for what I get...though footprint and output are...and pretty much I think wick types are the only kind I'll consider now. And, brand isn't necessarily a requirement...though past experience with other brands has made me leary of others. Plus there's feature differences. Some do take less space, but only have one tank. But, I'm running this single humidifier to try to humidify my entire condo...so it does have to be big as well... But, have time before I have to complete the order...so reviewing all the results....wouldn't be so painful if amazon's search was so fuzzy. I'm searching for just "humidifier", and its showing me things like cribs, pillows, swaddles, bassinets, dehumidifiers, evaporator coolers, air purifiers, bottle brush, nipple cleaner, heaters, bonsai tree, air conditioners...though the cigar related humidifiers probably aren't out of line, though I don't really think they should be in the department I'm searching under. And, the further out...finding humidifiers becomes less and less likely, but sometimes there'll be one here and there....though I'm sure if they weren't so fuzzy, I wouldn't have 10x the results to wade through....though sometimes the result is way near the end. But, not this time.

Anyways...that's pretty much what should just be in my amazon cart. But, if I add a few more items, I can get 6-month do not pay on my Amazon card....and I've already put off getting the humidifier too long already.

Now instead of subjecting some poor random forum to a long rambling thought, I will try to consolidate those things into this blog where they can be more easily ignored profess to be collected thoughts from my mind.
