Dual-Core P4 running HOT HOT HOT?!?
on Aug 21, 2005 at 12:49:06 pm

Anyone know what the "normal" running temps (idle & load) should be for a dual-core P4?

Here's my info:
--P4 830 running @ 68-73c after 1-2 hours (idle).
--Boots up in the low 60s!
--Using Zalman 7700cu HSF -- (120 mm fan @ normal speed on FanMate2)
--P5WD2 mobo running around 45c after 1-2 hours
--Running 3 case fans (@ default speed)
--4 HDD installed but no apps yet (only Win XP)!
--AeroCool 550w PSU

I've read dual-core P4s tend to run hot, but is mine too HOT?!? My system seems to be stable for the moment... and keep in mind that I just built this PC and its only run maybe a total of 10 hours at idle and low load... The CPU temp justs creeps up every hour....Arctic Silver website says it take 72-200 hours to break in... but I am thinking maybe I did NOT put enough AS5 for a dual-core CPU???

Arctic Silver website doesn't have specific instruction for a dual-core...
[I smeared AS5 to both the CPU & HSF using baggie/finger method. Then
wiped the surface off w/ lint-free cloth (coffee filter)...leaving AS5 in the
microsopic valleys, right? Then applied a tiny 1/2--2/3 of a BB glob to the
center of CPU. Dropped in Zalman, twisted 2 degress, then tightend]

ALSO: my mobo manual says this: "If installing a dual-core CPU, connect the chassis fan cable to the CHA_FAN1 connector to ensure system stability" I connected the HSF cable the CPU fan header...but do they mean I should really connect my HSF to the CHA_FAN1 connector?? I thought a chassis fan is a case fan...

Should I re-apply more Arctic Silver 5? OR doing something else?
I am very concerned! Please help before I fry my dualie!

There is a lot of info in the Asus MoBo Forum:

Happy editing.

You make it sound like you spread it on and wipe it off. You need enough so there is no air gaps between the CPU and Fan. Make sure your CPU fan is secured in place and has not loosend off the CPU.

I'll have to look and see what the temp of my Dual core is running at.

These chips do run hot... That is up there but not rediculous. But if that is not even under load, you may have some problem.

Try re-seating with more thermal grease. Make sure you are applying it correctly.

These problems can frequently be caused by not enough cool air flow. I know you have '3 case fans' but that doesn't really mean anything... It's the layout, how much air they are pushing, where they are pushing it to, etc.

I re-applied (more) Arctic Silver and reseated HSF... getting somewhat cooler temps , running 56-68C range now... The PC is now in a cooler room too, which helps but the themal grease still need many hours to break in...

I still have to test it under full load, but things are improving. Thanks for replies.
