Wow Wallace good find. That will work a lot better than one of those cooling fans you set your lappy on.

Oh yeah!
The CFM (cubic feet per minute) airflow of this fan is only 76.0 at 800 R.P.M., but I have 3 other fans I put on the case as well. I could have purchased a fan with a higher CFM, but it would also have a higher dB (decibel) rating and wouldn't be as quiet as this new fan I just installed. Any db rating above 20.0 is concerned loud and this fan has a rating of 18.0.
My computer case now has very good positive airflow, which is what I wanted to accomplish.

Strange setup... there are plenty of 12V sources inside a PC. All you need is a Y splitter for your Molex connectors if you haven't got any free ones left (rare). It is also quite likely that you have the adequate connector on your mother board, so you can monitor and even sometimes control the fan by software.

Wallace you should go into business with this kind of thing, you would be good at it, make some extra bucks.

Believe it or not, but I don't have a single molex connector coming from my power supply and the motherboard has only one 4 pin connection that's being used by the heatsink.
I'm also getting close to the power supply's limit on this machine. I know it sounds strange, but I also wired an inline switch onto the fan wire and all I need to do is flip the switch to turn it off.


Thanks Molly.
When I got out of the service I began working as an electrician. I did this for a long time until I started building furniture full time at my family's business. Building furniture was a hobby at the time. That was the last job I worked at.
Computers are fairly easy to me. All you have to do is plug everything in the right place and make sure you have enough power to run your stuff. Of course there's other variables to consider, but as long as everything is plugged in correctly it should work. Most of the time there's only one place for any given connection to plug in to that will fit.

Wallace, it is the variables that scare me. I don't even like taking the side off to blow out the cat hair, I did it a few weeks ago and now I can't get the screw lined up to put it together.

Sorry to hear that. Remember this... "Lefty Loosey, Righty Tighty"

A few exceptions exist, notably old propane cylinders and some pipe fittings.

I just can't get it to line up with the hole, but one of these days I will get down on the floor again and stand on my head to get at it.

Sounds like a sideshow act, if you ask me.

Wouldn't it be easier to move the computer from where it is, to say the kitchen table?
Did you blow out the dust where it is?
If so you're kind of defeating the purpose. The same dust plus new dust will only accumulate back into the machine.

What are we going to do with you Molly?

What are you talking about? I use that Dust Off... compressed gas duster, then I take my vac hose and suck any up that is around the pc. I don't want to take out the tower cuz there are too many friggin plugs to put back in. Another scary thang. I will tackle building a house completely but not the inside of a pc. Worse than stepping on a snake.

did you see my duster I posted above?

No, I'll look now...
I can't find any "duster"?
Sorry... Yes I see it now.
I have an electric duster called "DataVac". No more buying cans of compressed air for me.
I blow out my machine at least once a week using the DataVac, it's very dusty here in Arizona.

Do you treat your computer like veal?

What have you got going on in that case, Wallace?

What's generating the excessive heat? Are you overclocking? Have you tried liquid coolers?

Not overclocking, and IMO liquid coolers are a waste of money.
High-end video card and the CPU. It's the power supply that's creating most of the heat.
Temperatures haven't really gone out of the norm. Between 45-55c, but now I'm down to 32-40c, just with the addition of this new fan.

Hmm. in that case they are also Y splitters for SATA power connectors, and the power drain of a fan is negligible compared to your GPU. If it made a difference you would already have frequent power shutdowns due to overload.

And I would be very worried by the safety of two different current sources wired into the same machine, even to isolated and insulated parts. A French PC magazine also ran a test of varoius AC->DC converters for USB devices and no converter under $10 (7€) was even safe (no overcurrent protection, they would all catch fire rather easily in case of overload...). But well, that's your house

There is certainly nothing wrong with wanting your system to run as cool as possible. I've not used a liquid cooler but I know they're popular with overclockers. I've never really understood why people spend a lot of extra money on cooling so they can overclock their system, when they could just use that extra money to by faster components. I guess there must be some cost savings in certain instances.

My main system is also my media center so I'm interested in it staying cool, while remaining as quiet as possible. I don't use a case fan or a GPU fan. My power supply fan and CPU fan are both fairly quiet but not silent. I've seen a few fanless power supplies but I understand they have heat issues. My ideal media system would have no fans and use solid state drives, basically no moving parts.

Thanks for the warning.
I'm going to look into having all my fans connected to the power supply, for safety reasons. It's just a matter of picking up a few splitters.



I hear you.
I have two 120mm case fans and the new 200mm fan I just installed, one 120mm CPU and an 80mm GPU fan plus the power supply's fan, which is probably close to around 80 or 92mm.
With my AC set at 70°F my machine runs at temps between 27-35°C and without the AC the temps run a little just higher.
All in all that's pretty good.
The addition of this new fan really made a big difference, that I could see immediately. The whole system runs at about 20-25 db (which at times can seem like a chinese water torture) when everything is maxed out. I've gotten use to the sound and when I'm wearing earphones I can't hear it at all.
I'm going to add some potentiometers to the three case fans, so I can control the levels of output to them. There's an empty floppy disk bay I'm not using, with a cover plate. I'm going to mount all the pots to this cover plate, they will look factory installed when done.

I didn't think pc's came with floppy drives anymore. hmmm
