Sanyo Denki Ace, 80mm blue label Panaflow: Tested & Comp

Operandi · Post by **Operandi** » Wed Nov 10, 2004 10:30 pm

I'm looking at this Sanyo Denki http://store.yahoo.com/directron/ace25.html for my Alpha PAL8045. I'll be dropping the speed down to 1500-2000 from the 3000RPM top speed. I've heard good things about them in the past, anyone here have any experience with them?

Never heard of them. What does: "Bearing System: Mid SPEED-BALL BEARING" mean?

- Edit. Oh. Forget it.

Ball bearing.

I believe the Sanyo Denki Petit Ace is the one found on the Alpha 8952 (Quiet version). I'm not sure if this helps, but the fan was reviewed along with the heatsink on this site.

I went ahead and bought this http://www.thermalfx.com/merchant2/merc ... R0812M4011 SANYO DENKI, I'll post back after a bit of testing.

I also pick up one of these blue label Panaflows http://www.thermalfx.com/merchant2/merc ... =FBK08A12M, anyone have epxeriance with them?

I like them, but I run them at 5v, rather than the hardwired 12v that they come in.

Well whichever fan I decide to use I'll be running at reduced speed. Whats the fan running at under 5v (roughly)?

I've never tried running that fan at less than 5V.

Sorry, thats not what I ment.

How what RPM and how much air dose the fan move at 5v.

Both the Sanyo Denki and blue Panaflow arrived and I've spent a few hours testing both, 2:00AM testing, fun

. I should note that my testing was by no means scientific I only had one of each fans except for the L1A's. All testing was done in my Lian Li with everything un-powered expect for my Tagan PSU.

For comparison I had a L1A that I ran at 12v for most of the comparison since I knew at 12v the fan was running at 1900 RPM. I then dropped the Sanyo down to match and used the same speed % for the blue label panaflow. Since both fans have the same listed RPM at 12v they both should have been running at roughly the same speed using various %'s in my Silent Tek BIOS.

As for the results the Sanyo was extremely quiet and balanced very close to the L1A, I'm impressed. At speeds lower then 1000RPM I think the difference is somewhat more noticeable between the L1A and Sanyo, still very quite however.

The blue label Panaflow didn't fair as well, noticeably louder at all speeds and not nearly as well balanced. Not a bad fan by any means but it doesn’t compare to the Sanyo and Hdyrowave Panaflows.

operandi, did you give teh fans at least 24 hours of break-in before testing?

Operandi · Post by **Operandi** » Sat Nov 20, 2004 9:04 pm

No I didn't but the difference between the two fans is pretty significant, the panaflow was much louder. The Sanyo Denki was very balanced and exhibited almost no vibrations I'm assuming this relative to the noise of the fans?

Would it have made much of a difference?

I don't really have anything setup for a 24 break in period, I do have some spare Forton PSU's though so I guess I could if was determined enough.

It may make a huge difference, depending on the fans being tested; some change little over time, some change quite a bit.

Ok, I guess I'll let the fan run in for 24 hours and see what happens. I don't have very high expectations though.

Also, from your experience dose a well balanced fan always equal a low noise fan? The two quietest fans I’ve used the Sanyo Denki and L1A are both very well balanced.

It most definitely helps, but it's only one of several factors that affect how quiet/smooth a fan is. I'd say it's one of the more important factors, though.

I let the fan (blue Panaflow) run for over 36 hours while I was gone for a few days, for a break in period. I'm using the Sanyo on my Alpha now so I don't have that to do another direct comparison, but I don’t think that’s necessary.

From what I can tell it hasn't changed, at least not significantly. Fairly unbalanced and a decent amount of bearing noise at all voltages, I wouldn’t recommend it.

Thanks; that answers that!
