Uhm... you did. Or is that not your quote above? 😁
butjer1010 wrote on 2024-11-14, 21:54:Durons are the socket A CPUs that burns right in seconds when the fan stops spinning!!! What gives You this funny idea that he needs to use Durons????
Sure.
Care to show proof?Laws of physics (specifically, thermal transfer and thermal mass) simply don't work that way.
Stopping the fan for a few seconds won't do shit to the CPU, so long as the heatsink is still properly attached to it. It will take a good minute or more before the temperatures finally rise high enough to kill the CPU. That's because the heatsink has thermal mass, and it takes time to heat that up.
So NO, there's NO WAY the CPU will burn instantly IF the CPU heatsink is installed properly, regardless if the fan is running or not.butjer1010 wrote on 2024-11-14, 21:54:That is the only reason i suggested him XP Athlons, because they have this thermal diode that Durons don't have!
And so what?
As I mentioned, these thermal diodes aren't that good at reacting to over-temperature. If you're so trusting in them, why don't you show how that works with one of your own Athlon XP builds? I know I'm not willing to do that, because I've worked in the computer repair business long enough to have seen more than enough examples of how those thermal diodes specifically in socket A CPUs exactly don't really help more than anything else.As for the reason I suggested low-end Durons (600-900 MHz models): they have a much lower TDP compared to Athlon XP. For example, the 700 MHz Duron Spitfire has a typical power consumption of ~29 Watts and a maximum consumption of a little over 30 Watts. That means this CPU will be spitting out about 30 Watts of heat, tops. For the 900 MHz Duron Spitfire, that's about 40 Watts max. Now take O/P's Athlon XP 2100+: assuming it's the Palomino model, it has a typical power draw of about 65 Watts and a maximum power draw of 72 Watts. This is more than twice the heat dissipation compared to the 700 MHz Duron. So if using the same heatsink (with a stopped fan... or maybe just a badly clogged heatsink with dust), the 2100+ will be much quicker to overheat than both the 700 MHz or 900 MHz Durons. It's simple physics, and that's all there is to it.
butjer1010 wrote on 2024-11-14, 21:54:In nineties Intel had the comercial with Durons (if You remember those times, don't know when were You born), where they made fun out of AMD because of that reason. They used Duron in comercial, and they stopped the fan! After few seconds, the smoke came under the cooler, and they done that with Intel pentium also, but the pentium kept working fine! This was their way to people buy intel instead of AMD. So AMD made XP (extra protection) Athlons after that "fiasco"!!! They will not burn in second if the fan is problem....
No I don't remember that commercial (was there even one?), but I do remember the Tom's Hardware video from back in the day (mid 2000's) where they did this experiment with a Pentium 3, a Pentium 4, and two socket A CPUs (IIRC, one was a ceramic chip Athlon and the other a newer FCPGA Athlon/XP.)
In any case, stopping the fan for a few seconds will NOT damage the CPU - that's just myth / bullshit if such thing was ever shown in a commercial. Now removing the heatsink entirely from a socket A CPU or just not seating it properly on it, that surely will burn out the CPU in seconds.butjer1010 wrote on 2024-11-14, 21:54:After all he wrote up there, after all the things he has done, i think he is capable to put the cooler right, don't You think?
Not saying O/P is not capable of putting on the cooler right. But I have worked long enough in the electronics repair business to know that shit happens all the time and can happen to anyone, regardless of experience level. In my case as mentioned with the SV266A socket A motherboard that I was testing last week, the cooler retention simply was faulty and did not clamp onto the CPU properly anymore... though from a distance, it looked totally fine. It wasn't until I grabbed the whole motherboard by the cooler and noticed that it's actually wobbly and not tight / firm against the CPU. Not exactly sure how that happened, but I verified it several times. The retention spring was somehow damaged / bent out of shape. If I wasn't always double-checking everything like I always do, that CPU on the SV266A motherboard would surely have burned out.

Having an opinion is fine. But when it comes to troubleshooting, I like to work with facts only. So I don't take anything for granted until categorically verified.
So You're too Young to remember this commercial? Durons are worst AMD CPUs ever made (even though, first to reach 1GHz), but You don't remember that, or You was too young to remember.... Long enough in the computer repair business.... i see..... I overreacted and wrote - stop fan spinning (because they didn't work after few minutes without fan either), but in the "mocking commercial" they lifted up a cooler from Duron (1300 as far as i remember, 25+ Years ago), and he started to smoke few seconds after. But the point is, ask everybody here, older than aprox. 45 , and they will remember....
For the last part i agree, but still You can read between the lines and realize that this man worked with the oscilloscope on this board, somehow i'm doubting that he needs to check how the cpu cooler is oriented.... again, just my oppinion....
