Re: 2002-2012: A Decade of SPCR

Happy 10th! :D

I'm pleased to have been able to give back by writing the "superquiet superclocked" DIY articles based on what I learned here, and turned into a hobby. (500,000+ reads!)

I'm still running that system (upgraded a bunch of times), and it's still the quietest appliance in my house.

Re: PWM or voltregulated fans? Which is better?

4 pin fans can tick too, an arctic cooling pwm I was using in my htpc did that. Now fans can tick for other reasons too, but I think it was the working frequency of the pwm circuitry that did that as the ticking went away after I plugged it on another motherboard. I should have been more specific. ...

Re: PWM or voltregulated fans? Which is better?

Im especially thinking of the Noctua fans but i've heard pwm fans give a ticking motor noise from the pulses is this right? It's not that simple. There are two main kinds of fans: 3-pin and 4-pin. The 4-pin fans are generally referred to as PWM; they use the fourth pin to control the speed using a ...

Hmm, where to start. First, replace all the stock Antec fans with quieter ones. Any of those listed above will be quieter. All are 120mm.

Re: Need a quiet PC case for i7 build, moderate OC

The P280 is IMHO the worst choice listed. It was designed for ease-of-build, not silence. The P183 fixes many of the issues of the original P180 (especially lack of inlet cross-section) without reducing any of its sound reduction techniques.

Re: At which point is watercooling more quiet?

I would say that the crossover is approximately at a system power consumption of about 350W.

It doesn't look like anyone has tried this yet, my searches didn't yield any results, at least. I bought a MSI R5770 for quite cheap. Now I know it's because the fans have a bit of bearing chatter.

Re: Faint ticking from D12SL-12's and D14SL-12's. IS this no

You didn't say so, but I'll assume you're running these fans at less than full speed. On all but a few very high-end motherboards, 3-pin fan speed control is done with PWM (pulse-width modulation, aka duty cycle) control, where the fan voltage is switched between 12V and 0V in a square wave.

Re: Of fans, RPM, motherboards and 4-pin vs 3 pin connection

Oh, boy. A bunch of things are getting mixed up here. First is the basic difference between 3-pin and 4-pin fans. 4-pin fans have a built-in circuit that controls the motor speed based on a signal carried by the fourth pin (the other three are ground, +12V, and sensor). They are generically called P...

Re: Heat issue after video card upgrade (Antec P180 case)

That GPU is dumping almost twice as much heat into your system as the CPU, and worse, dumping it at the bottom of the system, cooking everything else. You're probably going to have to rethink the whole approach. First, your stock P180 has only one fan-sized inlet (spot 4) to deal with over 300W of h...

Lots of good choices. Depends on your needs for size and price.

Re: Unexplainable tempurature rise from 2500k

When run with default settings, most variants of Prime95 (eg, OCCT) alternate between small and large FFTs. Small FFTs generally fit in the CPU cache and run hotter. Large FFTs thrash the cache, so the CPU cores spend more time waiting on memory fetches.

In current PCs, 2x4GB is better than 4x2GB.
