I am seeing an appreciable drop in temps. While changing the fans I left the rig running and the heat did not spike at all...a tribute to the Thermochill PA 160. It got to 52C before I had the San Ac up and running and took quite a while for the temps to get back down...which I found curious.
Temps have slowly dropeed to 44C--a 6C decrease over the SilenX--but I am going to let it cook for awhile to be fair and let it have a good chance to drop all the way down.
The San Ace is not as loud as I feared. It does make a lot more noise than the SilenX but is is not an entirely unpleasant noise--kind of like a shop vac running...
At first I had a fingerguard in place as I was a bit nervous of the very sharp and sturdy blades impacting something and slicing it up--but the grill made a seriously annoying whine...I removed it and the fan was much more tolerable.
From the shots below you can see the set up.
The latest is the CPU temp flutters back and forth between 44-48C...staying at 47C for most of the time.
TBH I would not be able to put up with this amount of noise 24/7\\...the SilenX I could deal with--and even on low when it is inaudible it still keeps the CPU well within spec.
To get another 2-5 C at the expense of a reasonable and quiet compouting environment is too great a cost. No doubt on some other rad (HW LAbs
) the difference would be much greater.
Already it is clear that the application will make the greatest differnce to how one perceives the performance of a fan.
At this point I could go ballistic and run a huge Sig on XS saying "Don't Buy San Ace Fans" because I just blew $57 bucks and they aren't cooling that much more than my SilenX...
But I will let the San Ace blow for a while to see what is going on.
Just now the CPU temp went to 49C for a moment then 48C so it is really not but a degree or too cooler than the SilenX. It seems that 47C is where it stays mostly.
I have to wonder if the PA 160 is going to repond to more air in a manner that will give us any results at all..maybe all the fans will run at 50-49C
Maybe it doesn't matter what fan you use--just make sure it's a PA 160
