View Full Version : A64 Stock Fan replacement?

I would like to buy a new fan to replace the one that comes with every A64. I believe they are all the same. How many cfm's does it require? I couldn't find any info on the specs of the stock fan. My main reason for replacing it is noise. It is quite noisy. I tested this by just unplugging it when it was running :D . Probably not the safest way but it worked.

I'm also considering just replacing the whole heatsink. Maybe with a Zalman 7700cu? I'm just a little concerned about the weight of it... What about the version that is mostly aluminium? Anybody had any problems with either of these? And if you have one, could you please post your temps?

From what I've gathered reading reviews and whatnot, the Zallman HS/F would be a great choice.
I'm currently using the TT silent boost which does a nice job also.

I have a Zalman CNPS-7700 CU for my FX53. It's silent allright :) Performance wise, it not the best though, 50-55 C for loaded situations and 40-45 C idle.

If you just want to replace the fan then I would go with a good Panaflo. I was also very happy with the Enermax fan that I used in my XP-90 review (http://www.nvnews.net/reviews/thermalright_xp-90/#fans).

What temps were you getting with stock cooling? Right now I idle at 39-44 C and 53-57 fully loaded. So about the same as you're getting with the 7700Cu. Do you know if the FX53 runs hotter normally than my 3500+ Newcastle? I'd think it would.

@Clay, yeah I was looking at panaflos but couldn't figure out which one to get. How many cfm's does it need to put out to do a good job cooling? Anyone know how many the stock AMD fan puts out?

I don't know for sure about the stock AMD fan CFM rating. However, if you're going to use any quality fan in place of it I'm sure it'll be sufficient. To be on the safe side I would want at least 40CFM from a fan.

So I think I am now leaning towards getting a Thermalright XP-90. I read through Clay's review again and it's looking better than the 7700cu. And it's cheaper and a lot lighter. Now I just have to decide on the fan. I'm going to be ordering from ncix.com and they have 2 panaflo 92mm fans. A low speed on and a high speed one. Specs on each below.

Low Speed (http://www.ncix.com/products/index.php?sku=13923&vpn=FBA09A12L&manufacture=Panasonic)
Size 92 x 92 x 25mm
Model #: FBA09A12L
Rated Voltage: 12
Operation Voltage: 7- 13.8
Rated Current: 110
Rated Input: 1.32w
Nominal Speed R/min: 2100
Airflow CFM: 42.7
Noise Dba: 27.0

High Speed (http://www.ncix.com/products/index.php?sku=13925&vpn=FBA09A12H&manufacture=Panasonic)
Size: 92 x 92 x 25mm
Model #: FBA09A12H
Rated Voltage: 12
Operation Voltage: 7- 13.8
Rated Current: 225
Rated Input: 2.70w
Nominal Speed R/min: 2850
Airflow CFM: 56.8
Noise Dba: 35.0

I noticed from Clay's review that the sunon fan he used had a cfm of 56 which is about the same as the high speed panaflo. But the panaflo is quieter at 35 dba whereas the sunon was 39 dba. How loud is 35 dba exactly? I really don't know and the reason I want to get this is mostly for noise so I would like quiet but also cool. Thanks for all the input so far.

my temps A64 3500+ with 7700Cu

CnQ enabled: idle = 29 degrees, stressed 42 degrees
CnQ disabled: idle = 36 degrees, stressed 42 degrees

I noticed from Clay's review that the sunon fan he used had a cfm of 56 which is about the same as the high speed panaflo. But the panaflo is quieter at 35 dba whereas the sunon was 39 dba.

dba is logarithmic scaled. meaning 6dba is twice as hard as 3dba (every 3dba the soundintensity doubles)

if the sunon was 39dba and the panaflo is 35dba is around 2.2~2.3x more silent than the sunon.

I've heard both those fans. The L series are very quiet, I wouldn't have any desire for anything quieter if it mean sacrificing performance. The H series isn't all that bad, but this is from your average overclockers perspective. I find it easily bearable, but that's me. The thing is though you're only likely to see 1-3C difference between the two. It's not going to effect your overclocking results, but if you want a cool system and can stand some noise compared to very little to almost none, then go with the H.

I never used Stock cooling. I used a watercooling setup from Coolermaster before this.
FX will run hotter than your 3500+, well 512KB more cache etc.

BTW, the temps I quoted with Cool n Quiet Off. With Cool n Quiet, the temps at idle go down to 30-34 degrees C.

I'm using the 7700AlCu & so far liking it.
my room is hot usually so i needed it badly .
when room temp is high & no A/C .. idle = 48c , stress=65c
with A/C its another story idle = ~ 30s , stress = ~45c

C'nQ off.

I vote for the XP90, I'm using one with a Panaflo M1A, and I have overclocked my rig from 2.2 to 2.5 (with a little bump in voltage 1.55) and my temps after running prime95 for about an hour come to only 47-48 degrees.. and I idle usually anywhere between 33-35 degrees.

not bad imo.

How are you using the M1A with the XP-90? Isn't the M1A a 120mm fan? Is there an adaptor that lets you use a 120mm fan?

You may also want to consider the XP-90C (solid copper instead of aluminum). It's about twice as heavy of course though. We have had a review slated for the XP-90C for a while now but we've yet to receive the review sample.

I concur w/the enermax fans. They are pretty good. Also, I'd take a Zalman 7000cu over a 7700cu. From what I hear the 7000 cools a bit better, though it's slightly noisier than the 120mm equipped 7700.
