I'd like to know how many of you experience your CPU fan going up in speed when using poser [any version], for what length of time and the level of noise you experience if it happens. Thanx in advance of any replies. The reason I ask is that I just had a new motherboard fitted and now the CPU fan goes off on one when using poser and once when using PS7, and it gets kinda noist when the Wife is watching TV. She moans about it you know ;-^) thefixer, poser coord.

Yes, I get the same thing. Not just Poser either - C4D does it especially well. Speed goes up from about 3800 rpm to over 5000 rpm, and the CPU temp goes up by about 5 degrees. The noise is quite noticeable, though I'm used to it now. The case fan switches in sometimes, as well. The wife uses her laptop and desktop in the same room (she often has both running simultaneously) so she can't complain fortunately :-)

I had a power supply meltdown last year when rendering something with a huge light set. The PSU was running close to tolerance as it was but Poser pushed it right over the edge.

Sounds strange. I have my computer in a room with 3 other systems running simultaneously, but no issues with interference. Here is a question though, you say the t.v. causes noise? Is the computer on the same power strip/supply as the t.v.? If so, you would want to change that. I use one power strip for each computer. Keep in mind, if you have ever seen the back label on electronic equipment, it is required by law to allow acceptance of interference. Your computer is probably just grabbing ambient noise from other cables on the strip. Obviously, anything that is CPU intensive is going to increase heat as the CPU uses more clock cycles on actual processing, which in turn, should cause the mobo to increase fan speed. Here is something I have found that works really well for me. I have the side panel of my system off, to increase the fresh air on the inside. Also, I have a desk fan blowing into the unit. My general rule is, a computer can never be kept too cool. As far as case fans, I took mine out. All they really seem to do is spread the hot air around inside the case, at the expense of more juice stolen from the mobo, and they are notoriously loud. I barely even hear the desk fan blowing! Hope some of this helps!

Just had a very bad experiance trying to fit water cooling. First broke motherboard trying to remove fan housing Duh!! Then when I fitted the fan radiators they leaked, spraying water all over the new board. After 2 days drying and new radiators I tried again. No leaks buit the board was damaged and it also blew my graphics card, an X800 pro. Not to happy at the moment, but atleast the machine is really quiet:)

The new Prescott core Intel chips run really hot. That means they need lots of cooling. Many new MoBos use variable speed fans. When you plug in Poser it going to make the CPU work more and the MoBo will crank up the fans. It's not going to hurt anything. You are just using more of the computer's capacity. (Getting your money's worth) If your computer has some miles on it you might dust out the inside. That helps fan effiency. Use compressed air and focus on the CPU cooling fins and Power Supply box. Don't use a household vacuum. They tend to create static electricity and computers don't like that. Nerd3D

I had the same problem, but a case fan fixed it.

If you have a new moBo it probably came with software that allows you to monitor temps and adjust fan speeds to suit. My fans are pretty much at idle when the CPU isn't busy but when I start a render the CPU temp climbs instantly and the fans all speed up accordingly (and become more audible). It's a big improvement over my old box which used to howl all the time, even when it wasn't doing anything.

A company called Zalman out of Korea makes many products to let your computer run quiet. Someone mentioned watercooling. Some watercooling systems can be actually louder than a out-of the-box Intel fan. I've seen one with *three* fan. The Reserator, water-cooled fanless CPU cooler, is impressive, and whisper quiet. I use this one, and it was very easy to install. The hardest part was finding distilled water. The downsides are it's not very portable, and it's expensive. Check out Zalman's wild "TNN 500AF- The world's first truly noiseless high-end computer case" Possibly the most expensive PC case available.

Well, I can recommend "Big Water" water cooling kit from Thermaltake. It has everything you need at a reasonable price ($100). I use an o/c'ed AMD64 with the kit. I mounted the radiator outside my window so my computer is deadly silent...
