CPU fan @ 3750RPM (aprx.) too slow for XP 2500+ ?

[NotoriousJTC]

I just got my PC back from being serviced, and also had an XP 2500 installed... It appears that it's running way too hot @ 70c idle, and the BIOS reports fan RPM's in the 3750 range...


It that way too slow for a CPU that operates at the speeds the XP 2500 does? I am using the stock (OE) HSF. I think it may be contributing (or the sole reason) to the excessive heat being generated. I don't know if the unit (HSF) has been damaged or it it's some sort of fitting/mounting problem.


Please lend a helping hand. Thanks.

uh...

Remount that heatsink with some thermal grease\paste.

My CPU fan is only running at about 2000 and I'm getting about 46 idle.

Did you check and make sure your heatsink is mounted properly? 70c is way too high for idle even w/ stock heatsink and fan. Make sure you don't have the heatsink on backward and it's making good contact w/ the core.

BTW, I'm using stock heatsink w/ my XP 2500+ and I get around 45c idle.

Guys, i had it taken to a shop to have it done. A-Power to be more specific (Pacific Northwesterners should know them to be a good reputable store), ive dealt with them many a time as well.


Anyways, im also suspecting a botched install job now. Taking back tomorrow to get them to diagnose and try to fix it. I vowed not to get into this do-it-yourself thing just yet for it usually results in more problems than results, at least for me.

You know, when you actually get good at this do it yourself stuff, it's probably cheaper in the end

The stock retail AMD heatsink is not a bad performer, some people overclock to 3200+ speeds at default voltage with them. You might just take a quick peek and see if the heatsink is oriented correctly, like this. If it's not, they messed up bad, and the right thing for them to do would be to give you a new CPU IMHO. Putting the CPU through a few overheats in order to melt the thermal pad into the large, angular gap between the CPU core and a backwards heatsink is not going to do it any good, if you know what I mean.

That said, remember that motherboards are generally calibrated to give you the readings you want to see (Asus: mid-40C area, because the customer will freak if they see 60C+ even if that's what the true on-core temperature is). Not knowing what brand/model/BIOS revision of motherboard you have, your "normal" temperature could indeed be anywhere from low 40's to high 60's.

edit: by the way, what method of measurement are you using? I hope we're not talking

SiSoft Sandra

or something...

Mobo: ASUS A7V333 using bios 1017 (latest).


I used the BIOS and Motherboard Monitor 5 to get the temp readings. Both reported similar numbers in the 70c range (give or take 2-3c). Speaking of Sandra, before i discovered the heat issue, i had already put the system through a "burn in" test using Sandra, and the system survived.

mine running ~3300rpm all the time, with a temp of 49C under load average, in non-oc condition.

Ahhh, A7V333. They tended to read higher than most. mechBgon investigates A7V333 temp reading, long ago They started fudging their BIOS lower after about the 1008 revision or so, since people were freaking out over realistic (~60C) temperature readings.

As a result, with the 1017 BIOS and a 2500+, 70C does sound a bit high for your board/BIOS/CPU. I suggest making sure QFan is disabled in the BIOS and ensure that the heatsink's installed in the correct direction. And if those are correct then you might want to look at your case ventilation next, because a heatsink can only cool with the air it's being given, and if that air is hot already...? Yeah. Try it with the side of the case removed and see if it drops towards the sub-60C range over the course of time.

If you get to wanting to use a different heatsink, it's not drastically difficult: overview with photos and even a video clip

Buy a ThermalTake Silent Boost and have them install that using AS5. And tell them to use ONLY a BB sized dot of AS5 and to spread it out on the core using whatever is clean.

They have a history, y'know But they're generally ok now!

The Zalman CNPS-7000A Cu is only $50 CAD at Anitec. But it looks like they maybe forgot thermal compound or installed your HSF slightly funny.

Take it back to the shop. You paid for someone else to do the work (correctly). Have them fix it.

my heatsink+fan = valcano 11+
cpu = 2500+
fan rpm = 1500rpm
temp = 56c
didn't use any thermal paste
