The absolute performance is only relevant if you're using the same CPU as the one under test (Intel Core i7 965). If you're using a less power hungry CPU, the result will be far better. Compare these numbers with those from silentpcreview's previous test setup, for example.

Radio Shack sells a pin extractor for the big 4-pin molex.

The standard for fan controllers is a 3-pin connector with 12V, ground, and speed (or 4-pins for PWM). Fans that come with 4-pin molex connectors are intended to be plugged into power supplies. It makes no difference which ground wire they use.

Yes, I have no idea why this is. It could be my Aerocool F6XT is the bad apple as it uses: 12Volt - Ground - Nothing - Nothing. To me, this makes sense if you are only going to do a 2 pin rheobus controller, right? I mean It kinda makes sense. I am learning that fan molex connector is different tha...

A couple questions...is there an optical drive installed (would one fit)? And does the X750 power supply fan spin up or does it stay in passive mode?

I like ntavlas's suggestion of a bottom fan. Another idea is to place a divider between the CPU and graphics card, so the intake and exhaust fans work in parallel rather than in series.

Presumably the small one is for a low power version (Sandy Bridge starts at only 35W). Instead of giving the customer better cooling, they instead shave a couple dollars of cost.

Another data point in this argument is the Antec 3480. This IS an ideal case for a fanless PSU - why ? - because the top compartment has a top ventilation grill (designed for the original Antec PSU.) Agreed. A passive power supply in that case is truly passive, not stealing system fan airflow. But ...

It's an interesting tradeoff between spending money on a flash cache and adding to system RAM. System RAM can be used as a cache, much faster than flash, but doesn't survive (non-hibernate) power cycles / reboots.

What's the easiest way to connect two PWM fans to two motherboard fan connectors, one 4-pin and one 3-pin, with the PWM control in common (seperate power and monitor)? My first thought was to use two standard PWM fan splitters, cutting unwanted wires and solder splicing, as needed. But perhaps there...

Another way would be to use a very simple 8-pin microcontroller.

that's a really strange request. I am trying to envision a need for that. I can't. why do you need it? If you're using a fan with extreme undervolting, down to 4V say, then the fan may not spin up, even though it runs just fine at 4V. So every time you power cycle the system, you have to remember t...

Are there any simple/cheap fan controllers that supply 12V at power on for a second or two, then switch to the selected voltage?

Will this fit in an Antec Solo?

Download speedfan and reduce fan speeds.

35W TDP for the lowest power version is excellent.

It's confusing because I understood that IPS panels have higher response times than TN ones, so are more likely to have this problem if that's what causes it. I can only guess that an IPS panel with a 5ms response time might have a better BTW/WTB time than a TN panel with a 5ms response time. Or el...

LCDs will never look as good as CRTs when motion (especially smooth scrolling) is involved. 120Hz should help but it isn't a common feature yet.

The Pentium Pro was the last Intel CPU to use a fixed voltage (3.3V). Starting with the Pentium II the motherboard is responsible for the CPU power supply. Originally motherboards used 5V as a source, later 12V. Ideally the PC power supply should transition to 12V only.

Is it only integrated graphics AMD motherboards that have the bug? If it were a widespread problem you'd think somebody would have noticed before now...

They added a reset button.

3.5" floppies are actually 90mm (3.54") wide. The disk itself is 85.8mm (3.38").

I woke up from a nap today with a startling revelation. I will share it with you, free of charge. The width of a 5.25" drive is 5.75". The width of a 3.5" drive is 4". The "drive size" refers to the width of FLOPPY DISKS - not drives! 2.5" drives are 2.75" wide. What does the 2.5" refer to? Good que...

It occurred to me that most OEMs use decent cases for their PCs, and loads of used/faulty PCs are thrown out all the time. I've also noticed that Compaq use removable chrome fan grills like these on a few of their PCs (which is certainly preferable to a stamped metal). What do you think about reusi...

I like "legacy" interfaces. There's something cool about being able to use a new peripheral with an old computer, or vice versa. I like the fact that the PC world doesn't have a Steve Jobs type dictator who can impose his idea of progress by stamping out anything old or inelegant.

Zenphic wrote:I usually prefer using the 5V molex mod.

Isn't it a problem that 5V is below the minimum start voltage for most fans? Not that it won't usually work, but it's out of spec and may not be 100% reliable.

That's what I figured. It's a pity they didn't make the standard 12V only, since every device needs a voltage regulator anyway.

The SATA power connector has 3.3V but I'm wondering if any drives actually use it.

Are there any gaming cards with fans which can run fan-off (at reasonable temperatures) when not doing 3D?
