  • Overclocking and Case cooling Thread

    I thought I'd start a new thread on this over here since these threads get buried over at the Matrox hardware forum.

    Well, Steve got me going and I finally made some modifications to my new case. With the case closed the temp would get up to 118 degF with the overclocking that I am doing.


    First I replaced the 80mm exhaust fan with a pair of Radio Shack Blowers. These things move an incredible amount of air.


    Then, I added a nice 92mm Sunon fan to the home made card cooler that I already had for the graphics cards. This one blows cool air right on the processor and across the top of the G400.


    Ok, with the blowers and extra 92mm fan the temp dropped to around 99 degF with the side cover on, not quite good enough...Heheheh
    So, out comes the Drill and the Electric Jigsaw. I cut a hole in the side and finished it off with a car speaker grill. I then lined the inside of the speaker grill with the thin foam air conditioner filter material to keep the dust out.
    The final result is a case temp around 84 degF or about 29 degC.

      Hi Paul,
      Do the lights dim in Albuquerque when you turn that thing on?

          Although I do not have pictures, I can tell you what I did with my computer.

          First off, I have an Addtronics 6896A Extra Series case: http://www.addtronics.com/6896a.htm . This case is very nice. It has room for 5 8x8cm fans and 1 6x6cm fan and one more 8x8cm fan can be added over the CPU with an optional adaptor. I am currently running 2 front case fans, sucking air into the case and 3 small 2cm fans on my hard drive cooler, also sucking in air.

          For interior curculation I have 2 Radio Shack turbine blowers. One is on the bottom of the case, by the expansion cards, that shoots air next to the cards to cause a nice little airflow. In my PCI slot next to my video card I have a 3DCool.com Super Slot fan, which takes all of that hot air by the video card and spits it out the back.

          I have then have a Step Thermodynamics cooled PIII 450 (running at 504-540 MHz, depending on how my V3 feels that days) that uses a 2 fan system. Fan in the power supply sucking air out of the case. I then attached the second RS Turbine blower on the side of the power supply. This fan takes any residue heat and shoots it into the uppermost 5 1/4 inch bay, where I have 2 8x8cm fans sucking the air out of the case.

          Total fan count: 13.
          Total noise with case off: A whole lot.
          Total noise with case on: A lot.
          Total noise with case on and put into my wooden desk cabinet with air vents: I can hear the music again!!!!

            Hey - too many fans spoil the broth...

            My PC has been playing up real bad the last couple of days, and after a hell of a lot of friggin' around, I think I solved the problems by DISCONNECTING two fans I added to the side of my PC. I think one of them is causing a lot of electrical interference or something, but I know that although my PC is now warmer, it's more reliable!

            Cheers,

            Steve

              Here is my case.



              By the way, that is a 17" monitor next to it!

              It has two 5" intake fans, two 4" outflow fans, and one 4" crossflow fan pointed toward the Canopus Pure 3DII and Marvel G200 PCI. I have heatsinks only on both cards. This case was originally a server case with a redundant 300w PS. I was lucky to get a proprietary PS from work, and converted it to ATX.

              The CPU temp on the AX6BC doesn't go above 90F even in So. CA during the summer. The Celeron 300A is oc'd to 464MHz.

                Steve C,

                Yeah I know, I am working on reducing the number of fans and the noise level. First thing I am going to do is get ride of the Radio Shack Turbine fans. They are nice, but very noisy. I am also adding Dynamat to the interior of the case to block out as much noise as possible. I already have the front and most of the side panels done, I need to do the top and backs now.

                Once I am done I will borrow a camera and try and get some pictures up on the forum. I will need some web space first, so anyone can help, I would appriciate it.

                    Nice case jeepman!! Looks like it has lots of potential.

                      well in case anyone overlooked this little know fact, moveing a lot of air in an enclosed space can cuase static charges to build up. properly ground your system frame ect.. sidepanles ect... learned this tid bit from when i was running ducting for a wood chip and sawdust colector. dam thing was generating some really bad static eltricity untill i grounded it. (enough to knock you on your ass if you toched it at the wrong time)any way run a wire from the metal frame work of your tower/case to the ground of your outlet/ or if your lucky you have a ground screw on your power strip.

                        Technicolorly, your computer's case should be grounded via the powersupply. But you are right, too much airflow can cause static electricity. I just hope no one goes crazy enough to pull that off in a computer case

                          Hey Genom,

                          Got any pictures of your setup???

                            Alright, here are pics of what my Intel system currently looks like:






                            Okay, I have taken out one of the ductings so you can get a better view, on the end of each duct, there is a nidec gamma 28 blowing fresh air directly to each one of the fans on the processor's heat sink. The fresh air is ducted through the bottom 3 1/2 inch drive bay through the fron of the case. I also have the PS fans reversed (yes, I have two in the PS), the bottom front case fan blows in, the fan behind the G200 is blowing out, and the fan on the top,back of the case is also blowing out. In all there are nine fans in my case. I have separated the ribbon cables into rows of 3 and 4 and bundled them together, and shortened them to length to tidy up the inside. My case is a ProCase Full Tower (It is HUGE).

                            The end result is my system (BH6, celery 300a, 128 PC100) now runs at 504 at 2.1 volts. It also does 464 at 1.85 volts. The case temp went down from a balmy 99 degrees to a cool 84 degrees when room temp is around 70 degrees. My processor usually runs right around 95 degrees (Measured with a Fluke thermoprobe, and an infrared thermometer). Also the noise is not too obtrusive, the system sits in my living room, and my wife can't stand the sound of loud fans all of the time, so I had to choose my fans carefully (those nidecs are actually pretty quiet), and this case squelches most of the noise, anyhow (and the side only comes off for cleaning and adding new hardware).

                              Just my comment on this cooling debacle. While some of you have enourmouse amounts of fans, just having a pile fo fans doesnt help much if you dont plan it right. I've got 4 fans and my case is at 84F with an ambient temp of 80. AND it's a small case (midtower Supermicro) and my CPU and gfc card ar OC'ed as well. So if you get the cables nicely tied and out of the way, and plan a good airflow pattern you'll have a quiet cool machine
                              A computer is like sex. Your never 100% sure what your doing but when all goes well, it feels REAL good.
