Attaching 80mm fan to original Athlon 2500 HSF
I'm looking for feedback on the idea of attaching a 80mm fan onto the
original HSF (Ajigo MF035-032) that came with my Athlon 2500 in order to get the full load temp down from 72C to around 60C. The original 60mm fan is rated at only 18.5CFM, which seems quite low. I could stick on a Vantec Stealth 80mm fan that runs quiter and pumps 27CFM, which is about 50% extra air flow. Is it possible that this would make enough difference to get me down about 10C? Or should I look for a better heat sink also? In case it matters, my case is 24C. If you want more info about my reasoning on all of this read on ... I currently have a Asus A7N8X Deluxe Rev. 2.0 with a Athlon XP 2500+ running at 200Mhz * 9.5 with the stock HSF. Unfortunately I'm already hitting temps of 72C on the diode (at full load), which I'm not comfortable with. Since I don't like noise, and I don't want to overclock anymore than right now, I'm not looking for a super powerfull HSF. I'm also one of those people you worries about the warranty, etc. and would rather stick to the manufacturers suggestions on what can be attached to the CPU. This means that I don't want to go over the recommened 300g weight of the HSF and I would like to stick with using a thermal pad instead of paste especially due to the danger of thermal pump out. Since the original heat sink is very close to 300g and is made of a copper base with aluminum fins bonded to it, I'm thinking that I'm probably not going to find a much better heatsink without going over the weight limit. Am I correct in assuming that weight to a large extent governs how good a heat sink can be (exluding poor designs, etc.). So if I'm not going to find a much better heatsink for my needs, it only makes sense that I simply change the fan, instead of getting a whole new combination and wasting money.

72C? If that is really your CPU temp. your HS is not mounted properly!
You'd better get that problem solved before your CPU becomes a keychain ornament. "Harry Muscle" wrote in message ...

You'd better get that problem solved before your CPU becomes a keychain ornament. It idles around 43C (this is the diode reading, not the socket which idles around 34C, and only goes to the mid 50s under full load). I'm using the original thermal pad, which might contribute a little to the heat, but I'm pretty sure the HSF is on properly (for example its quite hot, so heat is being transfered to it, but I'm thinking there's not enough airflow to get the heat away from it ... ie: my original post) Thanks, Harry -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

It's the reading of the internal diode when I'm running the CPU at full load (ie: prime95).

When I built my system some guy posted this... Do not use both W83L785T-S and W83L785T-S Diode (Asus 4) simultaneously in MBM or results will be incorrect. Ed Just checked, nope, it doesn't even allow me to pick both. If one is already selected, when I trying to select the other one for one of the other monitors ... it simply puts it back to none.

I've got two of them right behind the CPU sucking air out. Another in the front blowing air in. Case stays at a steady 24C. Room temp is 22C. I'm using 80mm case fans on 2 systems for CPU fans, but they have better heatsinks then the AMD PIB parts, at full loads the 80mm don't cool as good as the original fans do, at idle there is basically no difference. However, what if the 80mm fan delivers an extra 50% more airflow over the original 60mm? Or are you saying that the increased airflow wouldn't change anything? Ed P.S. Does anyone have a similar setup as me (Athlon 2500 with original HSF and thermal pad)? Could you share your temps with me (especially the internal diode temp as read by MBM5) after running prime95 for a couple of minutes on the max heat torture test setting.

I put a Vantec about two inches from the retail HSF and it dropped the temps 15C. That's a 2500+ @ 3200+. So your idea is a good one. The weight specs are only for PC's in transit like LAN boxes for gaming. The Volcano 11+ keeps one of my Bartons 2500+ @ 3200+ below 44C at all times. http://www.thermaltake.com/products/...nk/v11plus.htm ------------ When your PC gives a little they give a lot. http://www.dslreports.com/forum/disco |

Replace the stock HSF with a Thermalright SLK-800 or 900 with a nice and
quite Vantec Stealth fan and use thermal paste. If you can't buy the Stealth fan where you live, get a fan speed control unit to control the speed of whatever fan you decide to use. Vantec makes nice fan speed control units as well.... www.thermalright.com www.vantecusa.com "Harry Muscle" wrote in message ... "Ed" wrote in message ...
