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.

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.
