my brothers computer is running a rather old p4 1.8ghz (williamite) socket 423 cpu on an asus mobo with 768mb RD ram. i have a few questions: he has a thermaltake orb on it now, what is the normal running temp for this cpu with this cooler? how hot can it run? what is the best cooler for a socket 423 cpu? i know, i should google it first, but i can't seem to find much on socket 423. thx!

According to the link below your brother's P4 Willamette 1.8GHz has a maximum operating temperature of 78°C. Is his system overheating and what numbers are being reported with that cooler ? http://www.heatsink-guide.com/content.php?content=maxtemp.shtml When Google isn't your best pal

Wow, socket 423's are quite old. I don't know any 3rd party coolers for that socket... In fact, this is the first time I have came accross this socket. I always thought P4's ran on socket 478 and 775.. Sapphire PC-A9RD480Adv Sapphire Radeon X850CF AMD Athlon 3700+ 2.63GHz 350W Acetech PSU 18A 300W SP PSU 16A

Instead of thinking about a new cooler, case temperature and dryed up thermaltake can lead to high temeratures.. Solution, take out the heatsink and scrub away old thermalpaste, add in arctic silver 5 and ensure a good air flow throughout ur case... Pentium 4 has a built-in thermal monitor that when the temperature reach beyond mid and high 70s, it will start to throttle down so if your CPU is not throttle, I would not worry about temperatures... go to yahoo and search for "throttlewatch"...

Thermalpaste I meant... lol TMP-Man Asus P5P800-SE P4 506 2.66Ghz @ 4100Mhz 1.525v Thermaltake CLP0024 w/ 2000RPM FAN 1024MB DC Corsair DDR400 40GB 5400RPM/120GB 7200RPM HD 128MB Radoen 9500 mod 9700 @ 360/585

ya, i know. it is old, but it runs pretty quick the bios is reporting around 43 degrees C, and i just didn't know how hot it could get before i worry. i think i found a pretty swell heatsink and fan for it: swiftech MCX462-U heatsink vantec 80mm tornado fan ya, i know, the vantec tornado is ear-peircing, but we don't mind. thx for ur help everyone Toshiba M50-MX2: Celeron M 1.5GHZ 1MB L2 512 DDR2 PC4200 RAM 60GB 5400RPM HDD DVD+/-RW CDRW DVD-RAM

you wont mind the tornado for about..a week..and itll start to drive you nuts..try doing as TMP-MAN suggested and pull off the heatsink you have now and replace the thermal paste and clean the heatsink..and by the way..that isn't a terrible cpu temperature by any means Gigabyte GA-K8NS Athlon64 3000+ Newcastle Zalman CNPS7000B-Cu X800XL 256MB AGP 1GB Corsair VS 120GB WD/160GB Maxtor Aspire Chameleon 550W
