Overheating PC, athlon classic 750, need some help 1

Okay, this is the setup Ive got:
Asus Kv133 motherboard
athlon classic 750 processor
128 mb of ram (Ive upgraded now to 256)
soundblaster live Xgamer
matrox g400 graphics card
maxtor 20 gig harddrive
USR 56k hardware modem
iomega zip drive
atx case w/250 watt power supply.

I have a dual boot system with win2k/rh6.2

Okay, this is where it starts to get fun. I bought this sytem in July from a company called computek. They let me pick my parts and put it all together for me and gave me a 2 year parts and labor warranty. I got the thing home and it black screened on me in 2 hours, wouldnt get past post. I was over at a friends house, we were gonna install linux on it together. I brought it home and tryed to turn it on again, and low and behold it started up. Checking the bios settings it turns out the thing will crash if the motherboard temp goes over about 95 degrees. The monitor for the cpu isnt hooked up so I dont know what that temp is. So I said what the heck, opened the case up, stuck a desktop fan on it and installed everything. Everything went in fine and its happy, as long as that desk fan is blowing right at the cpu.

So the next day I called tech support of computek. I talked to the same guy who sold me my PC. He said he would look into some cooling options for me and call me back in a few days. I never got that call. Now, Im a CIS major, in my senior year. I need my computer for homework and stuff. I figured, its working, what the heck. I should have just taken it back right then, but I didnt want to be without a computer for another few weeks. This was around aug. 8th. 2 or 3 months later I had a day off from school/work and the dumb thing crashed on me, nice memory dump in linux, about 3 times. I rebooted into windows to see if I could figure out whatwas going on, and it crashed there too. I had turned my fan down to low, guess it had to be on high. I turned the deskfan onto high, and it was stable again. Said screw this, packed it up and took it back that day.

2 weeks later I get my pc back. They told me they put a new fan on the cpu and actually put paste between the cpu and heatsink this time. (guess they forgot the first time)
and they had windows running stable for a day. I took it home, decided to test it out, put decent 3 in and played for awhile. Sure enough, about 3 hours later, bios is saying motherboard is hot, and win2k is giving me blue screens and shutdowns. I open it back up and stick the fan on it again. ah well. its a little better. Once the desk fan was back on the cpu, it was fine again. No more crashes.

This weekend I bought a new 19 inch monitor. The deskfan makes the monitor trip out, so it cant be there anymore.
I know everyone else gets to have a pc that they can actually put the lid of the case on. I want one too.

I just got off the phone with my tech support people. I ended up speaking with the same guy who sold me my computer. He told me that athlons run hot and there is nothing I can do. I told him to check and make sure the cpu hasnt been damaged from the heat, because it should be able to take more heat than what it currently does. He said that he has only built 2 athlon systems, one being mine, and the other one over heated too. The other guy brought his system in a few days after he got and replaced it with a pIII system and has had no more problems. The guy told me that I'd have to pay for a new motherboard and processor, go to a pIII and that is the only thing that will stop my problems.

Ive got 5 fans in this thing right now. The power supply fan, the fan on the cpu, the chassi fan they installed, a fan in the front 5.25 drive and fan going out one of the back pci slots. I still crash in linux and windows whenever I do anything processor intensive if I dont have the fan on. Making mp3s, compiling, games and such.

I need some advice. I know the asus board is decent and other people have good working athlon machines. I need to be able to close the case and put the case into my desk where it belongs.

Thank you.
 
Hunt the guy down, and shoot him. X-) (just kidding).
Rip the stupid stock fan off it, take it back to the shop, and get him to purchase an "orb" fan/heatsink for it.
Silver will probably work, but the goldenOrb is a great setup. You may have to pay the difference in price (maybe about $20, if that), but it will keep your AMD twice as cool as the stock fan/hs. Cheers,

Lynnfriel,

the length of your post indicates a lot of frustration, and understandably so !
I have no experience with Athlons, but i have been tinkering with overclocked CPU's, which have a tendency to start glowing as well.
Is your case amply provided with ventilation openings ? Otherwise, all those nice fans will only blow around hot air inside the case. Also, as both Comtech and jeromec suggested, an apropriate, force-cooled heatsink is very important, and it should be mounted properly, using some form of heat conductor (either paste or a silicone pad).
If for some reason your case can't get rid of the hot air you might consider installing a case fan; most cases offer a mounting for this. It seems to me that's a more practical solution than your desk fan !

Good luck !
 
Actually the Orb is a poor performer for cooling as later proven, looks cool enough, but it also damages your Athlons if you are not careful.

Thanx for all the advice guys.
Just to note, RonaldB, I have a 'case fan' or chassi fan already installed. I went home last night, and brought the whole case in to another hardware dealer that I found out of microtimes. Their add offered a lot of athlon setups and such, so I figured if they can keep theirs cold, maybe they can advise me on mine! I brought it in and we looked at it. He said I have a fan almost everywhere that I could possibly have a fan in the case I have. (They gave me a cheesy crap case as well of course). I ended up buying a much nicer, midtower case with 300 watt power supply. I havent put it together yet. One interesting note is that the guys DIDNT put any paste between the cpu and the heatsink/fan. In fact the label is still there. As the guy I spoke to last night mentioned, paper isnt exactly the best heat conductor around. He gave me some of that paste to put between my heatsink/fan. The new case has a spot to put a fan right in front of where the CPU is. Im going to have all my inside fans blowing air IN and let the powersupply pull the air out. The new case should also be tighter and therefore more air flow would be going across the CPU. I wont know how this works until tonight of course when I get home and put it all together. Re the golden orb, they didnt carry golden orbs for the slot athlons at the place I was last night. Neither did pcclub, compUSA or circit city. I was going to look into getting one from online. So, can you clear this golden orb matter up for us kb244? Give us a link to your source :)

Thanx for all the help guys.
After being told by tech support I was gonna have to fork out for a new CPU/motherboard I was a bit irrate yesterday!

"I’m sure that you’ve read ThermalTake’s story hundreds and hundred’s of times so I won’t bore you by going over the whole thing again. Thermaltake’s Golden Orb killed many a Socket A processor before ThermalTake brought out it’s Chrome Orb."

there was another review comparing some of the top Coolers, and the Orb came out second to last.

Thanks kb244, interesting reading. I guess I should have recommended the ChromeOrb, not the gold. X-)

To continue the original thought...If you read a few more articles, especially those having to do with overclocking the AMD stuff, you'll find that MOST guys prefer having the fans suck air OUT of the case to create negative pressure, and pull the hot air out as quickly as possible. Having fans blow into the case causes positive air pressure, and retains the heat in the case longer because it cannot escape. Please rethink your options on this, before mounting all those fans.
FYI, I have 5 80cm fans plus the PS fan, and CPU cooler. I have 3 (plus the PS) blowing out, and 2 blowing in. It runs my silly Celermine (600@1125mhz, 1.7v) at 125mhz FSB @ 32 celcius. Not bad for a 66mhz chip huh? Cheers,

actually

check that out, it compares 17 of the best coolers, turns out that none of the ORBs is the best, instead it's the Swiftech MC370-0A

"The costly produced Swiftech turned out to be the candidate with the best cooling performance. It gave us a low CPU temperature of 35 degrees. The class A fan from Pabst brings enough air flow which unfortunately leads to a lot of noise. The body made of single aluminum parts is unique. Therefore, the weight goes up to 316 grams and this model also infringes the AMD specs. No question: This cooler is first choice for overclockers!
"

and as you can see from the picture of that particular cooler, it uses aluminum rods (they do have a hollow copper rods version) which allows cooling to be performed better.

I'm thinking about getting their hollowed copper one, which cools even better.

oh on the next page, this is where it says Orb is not good at all, any model for that matter


"Both make a difference with their special design: The radial body promises a good cooling. Reality shows that it is not the case. Performance is below average. Both models have a good reputation among overclockers but the design is not optimal.

Both models turn out to be optical show makers. Furthermore, there might be the case that these coolers cannot be installed on some mainboards due to their size.

no actually you want(As shown in the review)

the MC462 is only if your motherboard is equiped for the new mounting method (of screwing right into the board)
