At full voltage the Papst is definitely audible within a 3 meter range, mostly airflow noise. The 4412F2/GL (with tacho) spinning at 900rpm is VERY quiet, almost inaudible in a case. In my book it is THE best 120mm fan available. I haven't tried it on a radiator, but I would think at 7v the Papst wo...

Was that card made by ATI or another vendor? Not all vendors use the same quality components for the "same" ATI chipset card, and it would be nice to know which vendor had the problem with the 9500 Pro , and if it was the same vendor who made the 9600 Pro. It is an original ATI retail box card. As ...

I've tried both the Super Silencer 400 and the Super Tornado 400 (both rev A2) in a system with an ATI Radeon 9500 Pro w/MagicGFX@7v and the loud high-pitched squeal from the PSUs is unbearable! Switched to a 9600 Pro and the noise disappeared. I guess the Seasonics don't work well with the 9500 Pro...

What is the full stepping code for your Mobile 2500+?

This just shows how much the "Antec" vents contribute to the cooling of the Sonata system. With the vents closed, temps would rise between 4-8 degrees. So with the Sonata, all fans could be operated at a lower rpm and still achieve good thermal performance, but the Antec vents would allow some noise...

Hmm, interesting. I would have expected the results to be flip-flopped in favor of the Chenbro. So did I, Ralf. In fact I even remounted the heatsink with a fresh application of AS5 but the results were the same. I'm actually quite disappointed with the Chenbro, since it is a far superior case when...

I thought I'd share some of my experiences with the two cases. All components are the same except for the addition of NoVibes III in the Xpider: XP1700+(200x10@1.475v), SLK900A/Panaflo 92LB1X@1600rpm, 8RDA+, 256x2 Corsair @2-3-2-12, Radeon 9500Pro w/MagicGFX@7v, 180GXP, Zalman 400w PSU, Papst 4412F/...

And something always goes wrong... especially building a quiet one...

The system shuts itself down immediately after I press the power ON button. I can't even get to Bios beep, it all happens within a second or so. The same happened here with the unit I returned, which I did not mention earlier on in this thread. I'm pretty certain your unit is defective. :( BTW, I k...

I agree. Having used Barracuda IVs exclusively before being discontinued, I took the plunge like you did and bought the 180GXP, and then 2x 7K250. I'll take the Hitachi drives anytime over the Seagate 7200.7 for one good reason: AAM. Even with AAM disabled, seek noise is far less obstrusive on the H...

I've just installed the NoiseControl MagicGFX on an ATI Radeon 9500 Pro and it's great! The 60mm Papst fan is all but inaudible at 7V. Very easy to install but only compatible with 9500/9700 reference design cards. Highly recommended for those not comfortable installing the Zalmans or ACVS. Performa...

But... Which fan stop spinning? Inside fan normally do not have to spin unless psu gets hot (60% psu load according to Tagan) The outside fan was what I was referring to. The inside fan never did come on in this system, even during extreme loads and high temp due to the failed outside fan, which le...

Cyberpukish,

If you're referring to the Zalman 7000 series, it is an integrated heatsink and fan design. The package includes the Zalman Fanmate too.

Mmm... I don't understand whats your problem. CPU idle temperature raises up due to a bad PSU ?? 70ºC?? Sorry for not elaborating on what's wrong with the PSU. The reason I said the fan circuitry was at fault is because the PSU fan would stop spinning or slow down to the point that it becomes ineff...

Update: The Tagan 480 is defective. Something to do with the fan control circuitry, me thinks. The defective unit was replaced with another that has the same noise issue. Me wonders if Tagans with the weird noise are prone to break down. My advice to all Tagan owners is to keep track of CPU and syst...

You're very welcome, Cyberpukish :D BTW, the Tagan 480 that I installed has begun to exhibit some heat problems. The PC would not start at all periodically and temperatures would shoot up. I suspect that the fan control circuitry is at fault. At times the idle CPU temp of the Pentium 2.4C would reac...

Cyberpukish, I would recommend the Zalman 7000AlCu if you don't want to mess around with fans. I personally prefer having the freedom to experiment and upgrade or replace broken fans, in which case the Thermalrights are the best choices. I've been getting mine from NEOKN in Singapore and I should me...

I wonder if it is a vibration problem for some of you. The Tagan is just a bit longerr than some power suplies. I have the Vantec silencer gasket on mine and rubber washers on the mounting screws. Definitely not a vibration problem, since I installed the Tagan on a similar Antec gasket with rubber ...

Well, MikeC recently gave a positive review of a 3.5" bay controller:

Not sure if you can get it in S'pore though...

I think I share the same opinion as many SPCR readers regarding Thermaltake products: STAY AWAY!!! Be very careful as to which fan controller you use, as most are PWM controllers which are very noisy. Since you're using the BQE and there are 4 5.25" drive bays, why not use one of them for your fan c...

I am now looking for panaflo 120mm fans they are hard to find here I wish I could help you with the panaflos, but I could only get the 80/92mm fans. If you've got the budget, the best 120mm fan would be the Papst 4412F2/GL. I've bought more than a half dozen and they are consistantly very quiet. Ho...

Wow, Cyberpukish, you're my neighbor! Michael Gan of NetWin Systems in Singapore, who is the distributor of Tagan, did mention to me that he carries the entire line. But I guess I must have wrongly assumed that it doesn't include the E-line; specifically the TG380-E00. BTW, which store in Singapore ...

the noise is only found in the 480 W models? Actually, reviews have indicated that the noise is found on both the TG480-U01 and the TG380-U01. However, according to Kostik, the TG380-E00 doesn't exhibit the noise. Too bad it's for the European market only. IMHO, the Seasonic Super Silencer 400 woul...

Very interesting! Too bad I didn't have mine long enough to witness the "break-in" period. How long did you use the Tagan before the noise disappeared?

Well it's good to know that you're happy with the Tagan!

IMHO, the Seasonic Super Silencer 400 would be the best bet. The Zalman 400A gets a little noisier when compared to the SS-400AGX when things get hot. So a well ventilated case is a must. I've recently installed a Tagan TG480 and it is VERY quiet except for a strange mechanical noise. It also runs a...

cosmo3, If your CPU and VGA fans are noisy, you most probably won't be able to hear the noise. But then again, you may have been lucky and got a unit that doesn't have the defect. In any case, when you have quiet down your system, please share your findings if the power supply has the mechanical noi...

Unfortuately, I did not have the system long enough to try to find a solution before it was sold. IMO there is probably no way to get rid of the noise. I'm in total agreement with Kostik; the noise isn't very loud, and the power supply is very quiet besides that. Hopefully, Tagan could solve this no...

halcyon,

The noise sounds as if the fan blades are hitting on something ever so lightly... but its not. I wouldn't characterize it as coil whine though.

I've just finished building a box with the TG480. I must say that the quality of the PSU is exceptional - twisted wires, exceptional finishing and attention to details. Power rails are incredibly stable, too. HOWEVER, there is a mechanical noise that is quite bothersome. I've initially thought that ...

Thanks, Ralf.
BTW, I've got the 7-pin audio connectors just like davidos. Could this be the "defective" batch that was the reason behind the delay for releasing the product? I find it hard to believe Antec would make such mistakes given their past success in case design.
