I had a pair of the non-PWM versions of that fan. Wasn't impressed... vibration was unusually high and there was more bearing noise that I'm used to hearing (compared to Scythe's FDB fans). I've mounted mine (PWM version) using vibration damping mountings, so I can't speak to that. I do agree with ...

Re: Arctic Cooling 120mm fluid dynamic bearing fans

I'm waiting for someone to try it out. :-P Why are you still waiting? There are plenty of posts about the 12025PWM by actual users. I have two. It is a decent fan, nothing great. You need to get it down to < 800 RPM before it could be considered inaudible. I've never tried it horizontally, but it s...

I‘ve replaced the fan with a Panaflo FBA08A12L that I picked up from Scan UK for about 50p and it easily cools my current CPU: The main problem with the Intel HSF has historically been the crappiness of the fan, not the effectiveness of the cooler. It seems like some of the more recent Intels act...

In SpeedFan, the reading labeled "CPU" comes from some motherboard sensor. It is unlikely to be particularly accurate. The readings labeled "Core0", "Core1", and so on, come from sensors inside the CPU and can be more reliable. Some CPU, especially certain AMD X2, are known to have terribly unreliab...

I think the problem with your "fat" tower concept is that it is not aesthetically pleasing to the general public. In general, people don't like looking at computer cases.

35C maximum operating temperature means the maximum temperature of the room, not the temperature inside the case. Naturally, the CPU will be somewhat hotter than 35C when it's working. Errr...

But that means that there's not much to get excited over the upgraded bronze rating. The lower the base draw, the less difference efficiency makes. If you had 26W-AC at 80% that should yield 25W-AC at 82%. Even assuming you were only at 75% before (more likely, since 80+ ratings are only good down ...

Re: DDR2 800 memory okay for Intel E7400 ?

I'm not sure I understand the processor guts well enough to understand the impact. The thing that seems to get people confused is that neither RAM nor CPU are advertised at their fundamental FSB clock speed. In the case of CPU, Intel advertises 4X the fundamental clock (eg 1066 => 266.7 MHz). DDR2 ...

If you need decent processing power, the best value proposition is an AM2 motherboard that supports undervolting coupled with an X2. With integrated graphics, a 2.5" drive, and a DC-DC PSU, your idle draw will be <30W.

It also seems like there are a lot of new high-end top-down coolers coming out lately. Scythe Zipang 2. Thermalright AXP-140. Thermaltake BigTyp 14 Pro. So, maybe the component manufacturers aren't as out of step as the OP supposes?

I voted variable, but feel that fixed is certainly better. It's just that fixed is only usable in a more constrained set of circumstances. You need the right components and ambient conditions. If you have them, then by all means go fixed. For the rest of us, there is variable.
