Re: You may not need as much wattage as you think.
So when looking at specs, do I add up all the 12 V rails? No. If there are multiple 12 V rails their sum is generally larger than the total power it can handle, you can't load all the rails to the max at the same time. The total 12V power is a separate specification. E.g. the example I linked (the ...

Re: You may not need as much wattage as you think.
Yeah, you're good. In general, there's one more thing to check: Power supplies may have multiple 12 V 'rails', say one for the mobo/CPU, one for a GPU, and one for molex/SATA power. Here's an arbitrary example from a 550W unit ( source ). Although it can deliver 550W in total, it's limited to 22 A *...

Re: You may not need as much wattage as you think.
... So where are the other 115 watts coming from then? Approximately: 22 W lost in the PSU at 90% efficiency (Gold) maybe 40 W for the motherboard (variable, 20-40W isn't uncommon, this includes conversion losses for powering the CPU. Higher-end mobos tend to use more power, partly due to having mo...

Re: This seems like a huge problem!
So under full load you should be at about 350W at stock speeds, 500W with max overclock on both CPU and GPU. I assume you plan on overclocking? And the computer is frequently under heavy load? If so, I agree: You need an ATX power supply from a noise perspective. IMO that rules out the Nano S, since...

What type of components do you have in mind? The Corsair SF600 is silent up to 120W and quiet (sub-20dB) up to 360W according to Corsair . It's very noisy at full load, but that will only matter if you draw that much power. At idle or with standard desktop tasks (mail, documents, internet, watching ...

Re: Noctua NF-P14 Fan?
Yes, I have one. It fits 120mm mount holes, but it's still a 140mm fan. If you can mount a 120mm fan and still have around 10mm extra space on each side, it should be fine.
The fan is quite noisy at full speed (1200 RPM), but barely audible when you use the supplied Ultra Low Noise adapter (750 RPM).

At which point is watercooling more quiet?
As far as I know, every CPU on the market can be cooled more quietly with air than with water. The same goes for any single graphics card up to and including GTX 580 (by using an aftermarket cooler). But if we keep adding graphics cards - dual, triple or quad GTX 580 - there will presumably be a poi...

Re: Intel Sandy Bridge Extreme: Core i7-3960X Processor
I'm not even sure if the primary purpose of the Extreme models is to actually be sold to someone.
I imagine it's mostly there for marketing purposes: To throw glory at its lesser siblings, and to make the rest of the lineup seem cheap in comparison.

Sounds good. Add any 2.5" drive and two sticks of RAM, and you're good to go. You might consider a Fan Mate or similar fan controller as well, the case fans may not run as quiet as you would like at stock speeds. You will still need a heat sink for the CPU, but may be able to skip the CPU fan. 35 W ...

Re: Water Cooling essential for quiet/efficiency? Really?
A six-core Sandy Bridge-E should use less power than a six-core 980X at the same frequency, true. But it's still 50% more cores than the likes of 2600K, and 4.5 GHz is a sizable overclock from a 3.2 GHz base, so I would expect power consumption to be closer to the 980X than the 2600K. But I guess we...

Stock graphics cards are rarely quiet even at idle. If you are certain that you want gaming-level graphics, your best bet is probably to go for an aftermarket cooler.

Re: Replace the cooling fans on my GTX 570
They look very similar judging from pictures, so I guess it's the same mounting mechanism.
You just loosen the screws. Finding the last screw took me a while: The red stripes in the middle of the casing, between the two fans, is a piece of metal foil that is glued on. The last screw is under it.

Re: Thermaltake Level 10 GT, 2600K/Z68, Corsair H60 and HD69
A quick update on queting the graphics card: Modding the card BIOS to lower the idle fan speeds seems unlikely to work, simply because the stock fans probably can't run any slower. The ~1200 RPM minimum speed is ~30% of the maximum speed, and checking the specs for a few PWM fans it appears that ver...

There's no VRM label in GPU-Z for my card (Asus HD 6950 DirectCU II), but there's "GPU #1", "GPU #2" and "GPU #3" with a couple of degrees between them, like 49 C, 50 C, 53 C.
Is it likely that one of them is the VRM temp? Can't see any other temperatures.
