| 294385 | 2004-11-21 20:04:00 | You also need to remember that the thunderbird core didnt have an on die temp diode, the temps your using is recorded by a small diode under the CPU. I'd add another 5-10 to any temp that diode reads out, I wouldnt be surprised if you CPU was closer to 66 degrees. | Pete O'Neil (250) | ||
| 294386 | 2004-11-21 20:44:00 | I rember reading on the AMD website that those CPU were OK up to a whopping 95 degrees. That said, I would be a bit concerned that you can't get the idle temp down to around 50. That indicates to me that there's not enough ait getting into the case (or being pulled out). Are you able to mount a case fan? Dick Smiths have one for around $16 that I installed in my PC and it's very quiet. Suck out from the rear / top of the case and/or blow in from the front / bottom. | POTUS (5276) | ||
| 294387 | 2004-11-21 20:57:00 | The issue is more to do with the design of the case. I already have an added case fan, however due to the location of the PSU, it traps a pocket of hot air which keeps recirculating. The only way around this is a) to get a new case, or b) to drill holes in the top of my case. | somebody (208) | ||
| 294388 | 2004-11-21 21:02:00 | Thanks Pete. One thing I am a bit concerned about is that I can actually grab the heatsink, and twist it about 1mm in each direction. This is with the clips all securely locked in place. Any advice on this? The temperature of the CPU stays within about 45degrees if I take the PSU out, and have the computer lying on the ground with the side panel off. This is because the PSU is one which sits vertically, and traps a pocket of hot air between the top of the case, the CPU, and the PSU, in a part of the case where there are no vents. |

| 294389 | 2004-11-21 21:17:00 | Is your case one of those stupid ones that has the PSU covering the HSF? Vertical as opposed to horizontal? Kill the case as quickly as possible they are horrible, a cheap Aopen or iCute can be picked up for under $100 and you should see instant reduction in temps. Without knowing what cooler you have i cant really coment on the movement of the HSF, as long as its making good contact with the CPU i wouldnt worry too much. Is it loose? or are you just able to twist? DSE have some cheap copper/aluminium coolers for around $30 that look to be alright value for money. Havent used one myself but they look pretty good. I would really really reckonmend getting a new case, try and find one with a 120mm fan in the front and mounting holes at the back for atleast one 80mm. That way you can have the 120mm sucking fresh air into the case and the 80mm blowing warm air out of the case. |

| 294390 | 2004-11-21 21:45:00 | Yes - my case is one of those annoying ones. I got the computer in question a number of years ago, before I knew enough to assemble a PC myself - I bought it pre-assembled, and it's caused me nothing but trouble. I think you're right, and I wil have to get a new case, but I will try whatever I can in the short term until I do. The HSF I have is the $16 SocketA Cooler from DSE here (www.dse.co.nz) . The contact seems ok as it was supplied with a tube of silver-oxide thermal grease, however the fan is very noisy when running at full speed. It doesn't seem to move around as much now, but it is still able to twist when some force is applied. |

| 294391 | 2004-11-21 22:02:00 | If you want a nice quite system the key is to use big fans at low speeds. Big fans at low speeds will push the same ammount of air as small fans at high speeds. But because the large fan is slower it makes less noise, if you choose your fan well then its possible to make then nearly silent yet still fairly effecient. All these attempt to reduce noise and increase cooling effeciency can be fairly costly, you need to rank the problems for "need to fix quickly" to "can fix at a later stage" and then set a budget. Theres no point spend hundreds of dollars trying to fix an older PC. A well chosen case may be able to last for a few years and several PC's, the same goes for quality fans. |
