Hi all,
my pc is making noises at boot up then the noise fades away...i am just trying to get to bottom if psu fan or cpu fan is near death.
my rendering temperatures are
cpu 136'f
motherboard 88'f
how does these compare with others?
cheers

I agree.
My system runs at 38 degC CPU and system at 25 degC whilst rendering.
Ambient temp in my home usually between 22 and 25 degC
The noise your hearing on boot up (presumably when first swiching your PC on) is grumbling/rumbling fan bearings caused by a build up of dirt and dust in your PC.
Get an aerosol air can from your local PC hardware store. Do not use a conventional hoover for cleaning, as you will possibly cause a static discharge into your PC effectively destoying it.
Remove the case from your PC and take the whole thing outside. Blast the grime away from all your fans usually situated in the Power supply, CPU heats sink fan assembly and possible your system clock chip on the PC motherboard.
Also, and most important, clean off any and all dust etc from your PC air intake and outlet filters/ports.
This will all help reduce you PC temp and improve things.
Hope this helps you............It's a lot cheaper than buying a new PC and should be done as preventative maintenance on your PC on a regular basis depending on how dusty the environment is arround your PC.
Regards Allan.

My system is currently running about 50C (about 122 F). I do think it is running hot (and that's with both side panels off). With the summer days coming up, I plan to get a small fan and just point it inside -- anyone ever do this? Any negatives I should watch out for???
At one point, it jumped to 65C -- I then got rid of some dust and a new fan, which brought it down to current levels. They say it's dangerous to vaccum those fans because of potential static build up -- I did it anyway -- I needed an excuse to replace this machine, but it didn't work (or it did work depending on how you look at it).

Yep I tried the Fan scenario, but ran into trouble. When the cover was off the case, the Fan motor created AC Harmonics, went into the motherboard and made my monitor appear as if it was a 1950 black and white. Once I covered the case up, the fan still running, only screwed it up half as much. I never did find a fan that wouldn’t give trouble, except for the 5 or 12 volt case fans.

What I did was clean all of the crap off with denatured alcohol and tooth brush, then got some soft aluminum sheets from the hardware store and built a funnel that I connected from the Front fan to the CPU. I then but another 80mm fan in the back of the case and had it exhaust. I put a triple Hard drive fan in a 5 ¼ opening. My temp dropped down to about 114 F.
After a few tests, I found my Power supply was under rated, I was running a 235 watt and should have had a 325 minimum for the new motherboard I put in. So I put in a 350 watt Antec and now am running cool again.

I am living in a place with an average room temperature of 30C & I don't have the luxury of installing aircon. My CPU always hover around 50C - normal work & shoots up to 70C when rendering. I bought a Thermaltake cooling fan to generate air in & 2 other normal fans to blow out. The cooling fan is temperature controlled & can spin at 5000rpm when needed. Naturally the noise level went up but who's complaining as long as the CPU & system are feeling cool.
I do my own maintenance every 6 months. I will remove all my optical drives, HDD, FD, VGA & all the PCI cards, and the fans. Then I use an anti-static brush on the MB. Never use vacuum cleaner unless you want to buy a new PC. Use an anti-static cloth to clean the contacts of all the cards & the RAM. For the fans, use cotton buds soaked in alcohol to remove the dust & grime. I will clean the CPU fan only once a year. Be very careful when you remove the CPU fan - use a long nosed plier to pull out the holding clip one by one & while holding on to the heatsink tightly. I ever pull the whole heatsink out once when it seems to got stuck & the CPU came flying out at the same time - got to replace it.

Peacefrog,
You didn't mention your cpu type (I didn't notice any mention).
There are many heatsinks available on the net to bring the temp down.
Us caution though, some only push air.
Whatever processor your using goto their website and lookup the specs
on the processor to see it's max temperature.
You must use high temperature heatsink compound between the
processor and the fan's heatsink.
The Intel processors with the extra cache ram run much hotter than
a processor with 512 cache.
When the intel processor gets to hot it starts to slow down.
The next step is a signal to the power supply to shutdown.
George,
I've always used an external fan blowing onto the harddrives.
Keeps mine cooler. Harddrives go through thermal re-calibration
while running, can't have that when working with audio/video unless
it's an IBM AV verified drive. An external fan blowing on the drives
makes a difference.

Never EVER run your P.C. without the side/font panels off for extended periods.
The reason being, is that these panels seal off the PC tower allowing the air to be recirculated arround the housing as the manufactures intended.
Air flow is carefully worked out in these housings, so that the air is pushed and pulled arround the casing in a ducted and controlled manner. Removing these covers is like sticking a fan somewhere in a living room and expecting it to cool down your CPU. It just doesn't work.
Stick to a well regimented cleaning routine, and/or replace and add to the CPU/tower fans with high flow after market fans (Thermaltlake to name one)
and the jobs a good un' as they say here in England.
Another tip :- if replacing the CPU heatsink & fan with an up-market one, use high quality thermal compound on the heatsink base. Arctic white is VERY good and available anywhere. Smear a small, repeat SMALL, amount of heat sink paste onto the bottom of the heatsink and scrape it across the bottom of the heatsink completely covering it, with the flatend edge of a craft/Stanley knife blade and press quite hard. The idea is to make as THIN a layer of paste over the bottom of the heatsink as possible. More is NOT definately better in this situation. Be careful when dragging/scraping the blade across the bottom of the heatsink. DO NOT scratch it.
Hope this all helps you guys.
Warm regards Allan.
