Well I've finally managed to get my system up and running w/ the Swifty 462 on here. After UPS took 6897 years to "deliver" (I had to pick it up just to get it AFTER they said it would be delivered) it, I ran into a few hiccups. All seems to be well now, barring that it didn't give me quite the temp decrease over the Fop38 I was hoping for...

...Last night I unhooked everything in my system and got the mobo out. My case is a mid-tower Antec so this HSF is a pain in the *** in that in mounts to the mobo. I installed exactly how Swiftech recommended, although not putting as much thought into making sure each screw was mounted correctly and evenly. I did use the shoulder grounding washers this first time. Also, when I had the proc out, I cleaned the core w/ rubbing alcohol and the ceramic w/ orange citrus degreaser as I read to do on Artic Silver's instruction page.
Now before w/ the Fop38 I ran my 800 Bird for over a month now at 10x100+. So you can imagine my horror when upon booting I couldn't even reach Windows w/ a multiplyer of 10! After removing the HS and checking my L1's, which I thought were OK w/ my conductive ink unlock, I again booted. This time I couldn't even use a multiplyer of 9.5, which worked before. After posting about this on some forums, I gave up and watched NYPD Blue.
This morning I got up at 8, and having to be at work at 10 wasn't even going to mess w/ it until this aftenoon. But I decided to give it another crack. I removed the fan, then the HS, and busted out the alcohol and degreaser. I scrubbed those L1's until I had all of the ink off, and re-applied it. My damn pen dried up on me though so I had to take a needle to it. Anyhow, upon booting I still could not OC. Screw it, I'll deal w/ it afte work...
...So after reading on some forums to NOT use the grounding standoff washers because they generally raise the HS off the core, I decided to try that. Bingo. I'm now running roughly 5c cooler than w/ the Fop38. At 70f/21c ish ambient, I ran 3dMark2k1 for an hour in a loop and MBM 5 reported 39c. With the Fop at that ambient, it would have been about 45c. I'll take those temps...

...as far as it interfering w/ my OC, I don't know. I re-did the L1's in pencil and am fine at 10x102. I think maybe some degreaser had nullified the ink or sumpthin'. Or maybe the off balance of the HS w/ those shoulder washers let the proc heat up to quickly. I'm open to theories here...

The only other thing I want to mention is that anyone who complains about the noise of this fan is a big *explative*. It may be rated at a higher db level than the Delta 60mm, but it's nowhere near as annoying. Where the Fop roars, this is a whirling noise. Even w/ the rheostat all the way up, which is where it was when I ran 3dMark2k1, it is not bad...

PS...if anyone knows how to loop the time demos in Q3v1.17, puleez lemme know...

Just curious as to what system board your using? I've got the KT7A- RAID with a 1.2T-Bird @266 (AVIA) with the MC462. Idle temps were at 44C which I thought were slightly high. Still having some troubles with the board so I have'nt really got to dig into it yet. (In the process of moving BIG PAIN!) anyway I'm using the grounding washers with the board maybe thats my problem.

I am using the MC-462A with a KT7A and I do use the nylon washers. Before I applied power, for the first time, I checked to make sure I could at least slip a sheet of paper in between the base and the standoffs when the screws were snugged up. That way, I felt secure that the base was resting on the core before it came to rest on the standoffs. That is the whole concern. As it was, I could slip a piece of 90 pound card stock in there, so I felt secure with the setup. Some motherboards plate and tin those holes. That adds to the overall height of them and in that case, you don't wan't to use the nylon washers between the standoff and the motherboard. That is how I understand it.
