My next step is to put a "Blow hole" in the top of my computer to take care of a case overheating problem, when using the CD or the DVD Drives.

Has anyone here done that? Any information from those who have, would be appreciated.

Thank you for your reply.

I got the info that the cd and dvd drives are causing over heating from the following web site. http://www.hardwaresecrets.com/article/143.

However my computer case over heats when I am ripping music from my CDs.
The processor runs at 100 percent capacity during the ripping procedure. I have a huge fan on the CPU heat sink, drawing air from outside of the side of the case, that adequately takes care of the CPU temp.

It is quite possible that the over heating is the result of extra heat caused by the CPU running at 100 %.

But I don't think it really matters, Because it is a new computer (about one month old) and I recently installed a fan in the front pulling air in and an additional fan in the back pulling air out, and that is not enough. My plan is to have the blow hole also functioning as an exhaust.

Being that the top of my case is not removable I assume that I will need to pull everything out of the case before I attempt to do any cutting?

At idle

CPU = 0 to 21 degrees Celsius = 32 to 70 degrees F.

System = 38 degrees Celsius = 99 degrees F.

HDD. = 22 degrees Celsius = 72 degrees F.

Ripping CDs


CPU = 8 to 21 degrees Celsius = 46.4 to 70 degrees F.

System = reaches a high of 51 degrees Celsius = 123.8 degrees F.

HDD. = 28 degrees Celsius = 82.4 degrees F.

First Let me thank you all for your input. It is all very helpful.

Starting with the last reply and working my way up. Thank you Doctor Kev. For letting me know what the average is. I am OK beginning with the average but not OK with staying there. I have not run across any evidence stating that having a cooler system can hurt the computer in any way, and it might help to eliminate the offensive odder that I smell when my computer runs at the higher temperature. No offense intended but average is just not acceptable for me.

minster...You have covered most of the things that I have thought about and provided some answers for some things that I have wanted to do. I took great interest in the Mounted 2 1/2" plastic 90 degree pipe drain fitting that you installed. How did you install it? I want to do something similar with the Blow hole. I want to mount the fan on top of the case, and mount a 90 degree fitting over the fan, facing towards the rear of the computer eliminating the need for concerns like dust,bugs,soda,etc.

Doby The link was very helpful.

Nick.

Upon taking a closer look at the sensor view window it is the Board or System that is giving the high reading. The AUX which has a picture of a case beside it reads 32 C = 90 F At idle. The system currently is reading at 41 C = 106 F

Thanks all for your replies.

Here is an update:

I installed a High performance case fan in the power supply, and it would not run it. So I powered the fan with an alternative power source, which has reduced the temperature by 4 degrees.

Currently I have a 300 watt power supply, next week I plan on purchasing a 400 or 450 watt power supply, and once that is installed, I will be installing more fans.

Yes Kev I will keep you posted.

Hi all,

I have installed a 500 watt power supply, cut two 3" holes in the case, and installed identical fans in those locations. One in the top (drawing air out) and one in the bottom, (drawing air in) The bottom one is centered approximately midway between the outside edges of the motherboard.

To accommodate the fan that draws air in from the bottom. I installed four casters in place of the plastic feet, which has lifted the bottom of the computer 2" above the surface it sits on.

While this has not dropped the case temperature, any lower than what it was with the high performance fan, that I had installed in the old power supply. It has improved the stability of the computer.

Although I have yet to put it to test under a heavy load, the temperature does not rise as high as it did before, when opening the resource heavy programs.

I used a variable speed hand held drill with a metal hole cutter. Not an easy task even for those with extensive power tool experience. I am pleased with the finished product, however it would have been a complete disaster with out the information in the link that was provide by Doby.

Thank you all.

Well for what I expect to be a final update to this thread. "For what it is worth". Yesterday I took an old hard drive apart, and cut a three inch hole in the base of it, and mounted the original fan from the old power supply to the bottom of it. Then I installed it in the bay directly beneath the hard drive.

It is taking the "intake" air that the fan in the front of the computer is providing and cooling the hard drive.

Currently my sensor view temperature readings are:

CPU fluctuating between 7 & 21 C.

Motherboard is fluctuating between 34 & 35 C.

Chipset is constant at 24 C.

Hard drive is at 20 C.

So over all a reasonable improvement. The greatest improvement is in the temperature of the chipset (down from 40 C.) and the hard drive ( down from 30 C.)

The mother board temp is down from 40 & 41 C. I would like to get it lower but I don't think it is possible.

Regards, and Merry Christmas everyone.

Thanks Minster,

Your temperatures are pretty impressive.

I removed all of the (non operating system) programs that the manufacturer had pre-installed on my system. Switched back to AVG anti virus from Avast, and I am seeing (after start up) a board temperature of 28 - 29 C. At a room temperature of 70 degrees F.

My computer has been on now for over an hour, and as I type this, the board temperature is reading 30 C.

That accomplished I now look forward to getting on with the rest of the things that I had plans for before this exercise began.

Your input in this thread helped to get my mind working in the right direction, and I appreciate that.
