that fan low front is pretty useless in ALL cases. It is too far away to blow over the hottest part of the computer (cpu) The graphics card blocks the air flow from this fan as well. So that fan only blows towards my empty PCI slots. It blows dusty air at that aswell, cos it sucks air from the only opening. (the carpet) I am hoping the make some fan contraption which will fit in the CD rom bay and blow across!

THANKYOU FOR ALL YOUR HELP GUYS. Feel free to keep posting info on how you cool down your case. p.s. I hope people dont think im a wierdo buying tights lol. This'll Be funny! Intel P4 3.00GHZ HT 800MHZ FSB 512MB PC2700 DDR SDRAM 128MB Radeon 9200 80GB 7200RPM SEAGATE BARRACUDA

the CD ROM bay would be the best spot for fans at the front of the case blowing across. It lines up with the back fans and CPU. Total airflow. I also thought of another reason why the front fan is useless. It blows hot air from the HDD('s) across into the case. Where would the fans be better placed: CDROM bay or down below? I know... do u?

You are kidding...right? Skip

well skippy, all i hear is critism, maybe u should explain how a low fan is better than a high one

I actually managed to wedge an old 80mm fan in my old pc case between the underside of my cdrom and the topside of my HD. This blew air over the cpu and towards the 80mm exhaust fan on the back of the case. It actually worked really well as it blows air over your RAM chips too, keeping them cool, and lowered my CPU temps quite a lot. ATX cases are badly designed as all the cool air at the bottom rises to the top and heats up and this is then fed into the CPU area, if you could get air into your case through one of the unused CD-rom spaces this will get cool air in to the case to blow over the cpu and ram and thus will significantly reduce temps. So Skip, don't disregard comments where you dont really know what you are talking about.

I ignored everyone (sorry) and got two L.E.D. multicolored fans. They arent too noisy and my temperatures have dropped from 30 - 32c Now down to 25 - 27 c! It probably will go up a bit if i game.

The largest difference I've seen in a case from bottom to top is 9°C. Typically, it is about 5-6°. Add on coolers to fit in 5.25" bays have been on the market for years (usually intended for hdd's) aand engineers have been working on cpu ducting that fits in these bays. See one on the market yet? CPU and motherboard temps are reported with a variety of diodes, resistors and thermistors and can be (and are) altered by the BIOS writers. These temps can be very inaccurate. When testing, I measure cpu, nb, sb, gpu and case temps with type k thermocouples to find out what's really going on in the box. If you think the airflow I described is bogus, just plug all your fans (except cpu) into a second powersupply and do a little testing with the fans running, then turn them off. nealwainwright, "I actually managed to wedge an old 80mm fan in my old pc case between the underside of my cdrom and the topside of my HD. This blew air over the cpu and towards the 80mm exhaust fan on the back of the case." Nothing wrong with that...even a small fan hung in the dead areas will help. "ATX cases are badly designed as all the cool air at the bottom rises to the top and heats up and this is then fed into the CPU area" This is not a function of case design, it is a law of physics. "if you could get air into your case through one of the unused CD-rom spaces this will get cool air in to the case to blow over the cpu and ram and thus will significantly reduce temps." No, it wont. It will tend to go directly toward the psu and rise as it warms up. The air would have to forced over the memory using a duct. "So Skip, don't disregard comments where you dont really know what you are talking about." Careful sonny, I've been doing this for quite some time. adamj555, "all i hear is critism, maybe u should explain how a low fan is better than a high one" You're the one who said "the CD ROM bay would be the best spot for fans at the front of the case blowing across. It lines up with the back fans and CPU. Total airflow." What about the stuff (everything in the rig) below that airflow? You will only exhaust a small amount of warm air. "I also thought of another reason why the front fan is useless. It blows hot air from the HDD('s) across into the case." That's the idea. Usually reduces hdd temps by 10-15°. Measured temps of air behind the hdd's show less than 1°C rise above ambient. If you take note of where sb, memory, nb, mosfets and voltage regulators are located on a motherboard, you can see the need for cool air to enter at the lower front of the case, pick up that generated heat and exhaust out the back. Cool air running across the top of the case is of little help. I may not know what I'm talking about but, I have done extensive testing with thermocouples glued and taped to about every location imaginable inside a pc. The configuration shown in the image above is the one that works and I have the data to back it up. Don't take my word for it. Do a google to see what AMD, Intel, and others say about airflow thru a case. Skip

Skip; After all the writing; you did not mention how you acquire the knowledge at such a young age. For a young "kid" you sure know more than others.

I have made the filter mentioned above i made it out of some stockings, trimmed around the edges and it looks good. It also doesnt restrict that much airflow beacuse i was told they were a low denier level. My CPU temp is still low. Im only a kid aswell lol.

Soon I think I will hack a nice big hole in my case to accomodate a 120mm fan on the top to act as a chimney above the cpu.

I agree. The only thing that low case fan is good for is keeping the dust out of your pc. Other than that it's pointless. TECHZAPORT OUT!!!

"I agree. The only thing that low case fan is good for is keeping the dust out of your pc. Other than that it's pointless." Actually I think it creates more dust because it sucks air from the front opening, which 4 me is the carpet

NEO123, Thought I'd add this one for the AMD fans. Skip

omg... are most of you people off your rockers?... or just let go of your mommies breast... having a fan at the low front is to pull cool air in and circulate it throughout the case and the psu fan in back as well as an exaust fan are to pull the hot air out.. no if the fans are level with each other then the air goes in out hole and out the other with out circulating.. that is why they are normaly at different levels to "circulate" the air.. cheap cases won't care about this and stick fan holes is horrible places... skip knows what he is talking about.. he has given tons of good advice to alot of people... and yes an intake fan will pull in dust, because there is dust in the air... no matter where the fan is located it will pull dust in... so NEO is doing good to want to filter the air that is brought into his case... good job... and skip... keep up the good work... even though I never could see the pictures that you are talking about...

"I STILL NEED TO KNOW HOW TO MAKE FILTER FOR MY 80MM CASE FAN" Usually the use of all caps is a sign of someone who just likes to yell but since this part of neo's question was ignored for several posts all caps seems justified in this one case. "I also thought of another reason why the front fan is useless. It blows hot air from the HDD('s) across into the case." You are spot off on that one. The goal of fans is to dissipate heat. That means to even out all temps everywhere. If the hard drive is hot you need to blow on it. Where it goes next is not a big deal. What is a big deal is getting air movement right up next to anything that is hot. "They arent too noisy and my temperatures have dropped from 30 - 32c Now down to 25 - 27 c!" Those temps are not realistic and you must have a bad sensor or a low ambient or software cooling. "and yes an intake fan will pull in dust, because there is dust in the air... no matter where the fan is located it will pull dust in" glad to see someone point this out.

i Think my temps are accurate seeing as i stuck a digital thermometer in the case for half hour and it read 26 c which is the same as aida32 reports for my mobo temp. I have always had low temps. My room is really cool aswell. with good ventilation. And it wasnt under any load, i have seen it get up to around 39c when i was playing a game once, but that was before i put my 2 case fans in and i dont do much gaming at all. Thanks for the compliment on the filter idea goldenknob. If anybody knows any other way to monitor my temps other than actually sticking my thermometer in there like i already done please let me know. Im sure they are accurate temps.

Take your car to a group of experienced mechanics and try to convince them that your engine is so good that it runs at 10C below its rated operating temperature. You might convince your friends at the pub, but none of the mechanics will believe you because they understand what is really happening in your engine. A computer is no different.

So you think im lying about putting a temp probe in and lying about aida32 and BIOS readings. do you think im some kind of retard.

johnoh didn't call you a liar...he said the temps are not realistic and they are not. BIOS readings are often way off and that's also where Aida32 gets it's information. Temp probes are another thing. They're usually relatively accurate if properly placed. In your case, that is not easy to do. Tell us where and how you placed your cpu's heat sensor. The old fan on the hdd is a good idea; just jack it up a bit to allow the air to flow over the drive. No one thinks you're a retard but you sure as hell did no research on P4 cpu temps or you would not have posted a ? asking if 31-32°C is too hot. lazyman has done extensive testing with several P4C and a P4E processor. Spend some time reading his articles and note what different bios revisions do with your temps, note his remarks about temp sensor placement and so forth. http://home.earthlink.net/~lazyman/ You need to spend more time reading and less time typing.

ok sorry (I think that shut me up, lol) I did do research but at the time I couldnt find anything decent. I didnt actually put the probe on the CPU i did it in the case to see my ambient temperature. So how would i place a sensor properly. In aida 32 it has what type of sensor it is if that helps.

iTS ABOUT 17- 18 C in the morning and when its cold outside. This afternoon i have come in and it was really warm in my room the temps have gone up to 36- 37 C. Which is the highest ive seen it go (although iv never really paid attention to temps until now) Thanks for the help on this subject. Thanks Skip for the compliment on my CPU fan hard drive idea.

You can use Speedfan, not only to monitor your temperatures, but also to control the speed of the fans. http://fileforum.betanews.com/detail/985582286/1 And Neo123, for a 3 ghz system, I also find it hard to believe that you can keep the temperatures down to 88 degrees F (32C). Unless, you have some sort of watercooling device hooked up to your computer. Tosh Hida
