AMD 5600+ runs too hot - why?
I just built an AMD 5600+ system (with the heatsink/fan that came in
the retail box) and when I was just going into the bios screens it heated up to over 80C - why? The CPU fan was running good and strong and the heatsink was too hot to touch - it nearly burned me when I just tapped it. I had to turn off the power right away. The case has a big 120mm fan and it was blowing real hard also - lots of air - the room was around 78F. When I installed the heatsink (which came with the thermal grease pre-applied), I pressed in on real good and I know it was making good contact becuase it was really hot. What could cause this CPU to run so hot? The power supply is an Ultra 600 watt. The board is an MSI micro and the case is the ultra microfly. I'm stumped - I sure can't run it that hot. Any ideas? |

It had a 24pin power supply and two 4pin CPU supplies (the 600 watt ultra power supply). The MSI board had a matching 24 pin receptacle and a matching 4 pin receptacle. They all fit like they were supposed to. I like your thoughts though - it must have been just too much current to the CPU - which means to me that the voltage was maybe too LOW, making it draw a lot more current. Current is what causes heat. I'm going to call AMD today and see what they say. |

Bad CPU or bad PS voltage regulation. Shat hippens. |

AMD 5600+ runs too hot - why?
I called the mboard manufacturer (MSI) and they said it was probably
due to some mistake I made in the BIOS setup program - he said there was an option there to change the voltage (to the CPU) and that was the ONLY way he could see how the CPU would get so hot, since I had good heatexchanger-cpu contact and the fans ran good. He said to elect "restore to optimal defaults" and so I did that an it has now been running for about 3 hours (under a very low load) at around 39C. So I guess he was right. I don't know what I did, but, like you said, "s**t happens". |

You peeled off that protective sheet from the thermal pad right?

I just ran Prime95 for about an hour and the temp reached a max of 40.1 C. Is that good, bad, average?????? Would it help or hurt to install a different heat exchanger? One of those thermaltake that get so much praise? I am not worried abou the temperature but I am finding that the LOUDEST part of the new PC is the stock CPU FAN. Would one of these better aftermarked heatexchanger/fans be quieter and maybe cooler (or at least no hotter)? Is there a better test to check out this system than Prime95? It is an AMD 5600+ with 2 gigs of ddr800 ram. I am very new to this newer technology (I was stuck back on 440BX and windows 98se) so I am open for any good information I can get. Will I gain anything noticeable by installing XP on top of win2000? What is mean is, does XP have any significant advantages over win2000 - it is more work but I don't mind if it gets me features I don't have with win2000. |

What is mean is, does XP have any significant advantages over win2000 - it is more work but I don't mind if it gets me features I don't have with win2000. WinXP Pro has several advantages over 2000. 1. It has a better memory management system, which will also give you a performance boost; unlike upgrading to Vista which actually runs slower than XP. 2. Remote desktop is a very useful feature of XP, if you want to login remotely to your computer. 3. The multiple user accounts and faster user switching is also another useful feature of XP, if you have a multi-user computer. 4. File encrypting and compression also I think are not available for Win 2000. 5. I think the network security has also been improved. Amyway, I was very pleased upgrading from 2000 to XP Pro. I would not recommend to anyone yet, upgrading from XP to Vista. Best wishes, Pete |
