This is most likely the real reason your 80mm fan is louder.

I must have that mini P180.

Speakers can pick up all kinds of noise. It comes from poorly shielded components, like a jack or wire. I don't really know what you could do about it, other than ignore it. I hear it when the speakers aren't playing anything, and I turn on a lamp or ceiling fan, or plug something in. This can creat...

But is Zalman's 18 dB as honest as Nexus 19 dB? Has anyone had problems going over the weight limit anyway? Nobody's sound level measurements are honest. If the Nexus has a 70mm fan turning at 2400 rpm, it will be quite loud. As you have said, a bigger fan running slower can generate the same airfl...

This has got to be my favorite Bluefront project thus far. Keep up the good work, and keep us posted!

BTW, can I hazard a guess that you are in the medical field as well, since not everyone would include "sphenoid" in their handle? --KK Actually, I'm in electrical engineering. Sphenoid came up in a materials science class one day, and I thought it sounded cool. It has the added benefit that it usua...

I was checking my F@H stats and saw that you were about to pass me. Little do you realize that I just got F@H up and running again! Unfortunately, my desktop doesn't have a dedicated internet connection, and I'm not around to connect it to download and return WU's. But the lappy should hold you off ...

A 650W psu could have a quiet fan, but most do not. We can speculate what the biggest problems are, but ultimately the OP will have to decide what the biggest sources of noise are. Also, the Raptor may be the most difficult component to quiet. Assuming he doesn't want to get rid of it, enclosures/su...

I think you would get the most improvement from, in decreasing order: new power supply gpu heatsink cpu heatsink You didn't mention what case and case fans you have. You might want to look into some of the fan control options on your motherboard. My LANparty UT 3 has some good options, and I would i...

The 28A number is much higher than actual usage. 28A at 12V is 336W, as you say, this is closer to system power consumption in the real world. So you should not have any problems with an S12-430. Or a 380, for that matter.

The flash recharge isn't terribly slow, maybe 5-10 seconds? I normally don't use a flash, so I'm not really used to having that delay. It is definitely a good value as well. I don't know if I would get one for my parents; even though it has full auto modes, it still has a lot of buttons and menus th...

I got my A570IS tonight and went out this evening to try it out What I like so far: Optical viewfinder in addition to LCD screen. Image stabilization! Lets me use handhold much longer exposures. Easy to change settings, most are 1-2 clicks away. Lots of adjustments, like focus, flash over/underexpos...

I don't think the power management features are that useful, either. Providing a rough estimate of power consumption is the more interesting feature of this product.

Dad's taxi was as stripped as stripped could be. 1 barrel 250CID 6 cylinder. 3 on the tree, no power steering, no power brakes, all drum brakes, and only an AM radio. And first gear had no synchronizer , can you spell G-R-I-N-D? You had to come to a complete stop in order to get into first gear wit...

I'll be spending several months in Belgium starting in July, and am trying to find out what I need to bring, and what I can get there. I want to look at some online retailers, but don't know of any. I'm looking for electronics stores, but also general merchandise places like amazon, places to buy cl...

I tried the A570IS today. I liked it. I don't know if it was quite as fast as an SLR, but not slow enough to be problematic. I liked that you could switch modes using the knob on top, rather than having to page through software menus. There are a few dedicated buttons, such as exposure compensation,...

The Canon A570IS seems like a pretty good fit for me. I'm going to try to look at one today or tomorrow and see how fast and ergonomic it is. Thanks for the advice so far. I looked at the Pentax, Nikon D40, and Digital Rebels, but I'm thinking of going the point and shoot route for portability/conve...

Let's see how much I can remember (I was young)... I got it in 1992 or 1993. It's been upgraded several times, and I still have it, although it hasn't been turned on in maybe a decade. Originally, I think the specs were: 486DX at 33MHz 16MB RAM 100MB HD 3.5" floppy 5.25" floppy Even then I remember ...

I used to be into 35mm photography, with a Canon SLR and slide film as my weapons of choice. But recently the latch holding the film back closed on my camera broke, and the increasing difficulty and cost of having film processed got me thinking about going digital. I can't afford a good digital SLR ...

I think the reason negative pressure cases accumulate more dust is a negative pressure case will pull air in from any openings. A positive pressure case only pulls air in through the fans, where dust filters can easily be installed. Filtering negative pressure cases is harder, because every opening ...

My laptop has this problem as well. It's a Dell Inspiron 5150 with a Pentium 4. I fixed it with Notebook Hardware Control. It seems more noticeable when the computer is running off the battery, so I set it to always run minimum speed on battery, and underclock it to 800MHz, since if I'm using the ba...

Is my carbon footprint different when I fly coach versus when I fly in the SPCR Gulfstream G550? It gets 0.86mpg.

What kind of noise levels does the SPCR jet make, anyway?

The efficiency will be much lower than a switched mode device. Also, why bother?

For my own education, is this what is happening in this circuit? The left side is connected to 12V, while the right is connected to 5V. While the capacitors are charging, the diode connecting the left and right sides is forward biased. During this time, the fans see an exponentially decreasing volta...

In that case, I don't know if I would bother with it. There will probably be a difference, but nothing spectacular. The extra ram will probably have more of an effect. But if money is tight, I don't think a new processor will make enough difference to be worthwhile.

Can you find a 2.4GHz chip? It probably only costs a bit more than a 2.0GHz one. I would definitely try to find the fastest chip so you can get the most improvement for your money. Other than that, make sure it's a compatible processor. Pentium 4's came in lots of flavors, for sockets 423 and 478. T...

I don't think it works exactly like a router, so both computers are on the same collision domain. Which means that if both computers are trying to use the internet, each can only work at half speed.

In my opinion we have got it right in the UK (in this one instance at least); the tax is on the fuel itself, so both gas-guzzlers and people who drive many, many miles have a big financial incentive to consume less. I also think this is the way to go. The same car can get vastly worse mileage when ...

I can't even count how many times I've been to Tom's Hardware and vowed never to return, only to be driven back out of boredom. I just didn't realize other people thought it sucked too.

That heatsink is pretty nice, especially for a scavenged one.
