Dell Loud FAN

[windowshacker]

I have a P4 2.80GHz cpu then i upgraded to a 3.80GHz P4 My computer is a dell dimension 4700 after installed the processor my fan is always loud its the cpu fan thats loud not the power supply's fan then i bought this http://www.ebay.com/itm/Dell-Dimension-8400-Fan-Shroud-Heatsink-T4307-W4254-/380509649427?pt=US_CPU_Fans_Heatsinks&hash=item5898247a13
i put that in and its still loud how to fix this thank you

Can you install a better HSF? Are you sure the one you bought is for the 3.8GHz CPU that probably generates a lot more heat than the original 2.8GHz CPU?

Yes thats for 3.2Ghz and faster and yes the cpu takes 115w and thats the best heatsink

Is there a setting in the BIOS to adjust the processor fan speed?

Nope Dell is crazy with limiting the BIOS

Just fan moving air loud or loud like it's scraping or vibrating something?

I've had those types make extra noise before because the clips don't hold the fan tight enough. Some electrical tape can usually fill the gap or even folded paper.

Everything is tight clips are tight no vibration

 

[GhislainG]

Did you check the CPU temperature? Is it high enough to justify full fan speed?

 

[windowshacker]

Pentium 4's don't have CPU temp checking but i felt the heat-sink and it was cool not warm cool

 

[Cazalan]

Have you tried cleaning off the fan with a can of compressed air?

 

[GhislainG]

If the BIOS won't allow setting Quiet (or whatever Dell calls it) mode, there may be a problem with the motherboard. Did the issue start before or after installing the 3.8GHz CPU? If after, does it work normally if you reinstall the 2.8GHZ CPU?

To help with diagnostic can you please state your original CPU model and current one - the problem can be in insufficient CPU heatsink, which has to be upgraded to cope with higher temps.

 

[windowshacker]

ok Sorry for me not telling the models the 2.80GHz Pentium 4 is model 520
The 3.80GHz Pentium model is 670
and i bought this heatsink to try to see if it can cool down so i bought this http://www.ebay.com/itm/Dell-Dimension-8400-Fan-Shroud-Heatsink-T4307-W4254-/380509649427?rt=nc&_trksid=p2047675.m1851&_trkparms=aid%3D222002%26algo%3DSIC.FIT%26ao%3D1%26asc%3D163%26meid%3D7408695415405052061%26pid%3D100005%26prg%3D1088%26rk%3D3%26sd%3D380420296016%26

 

[windowshacker]

the current one im using is the 3.80GHz Pentium 670

 

[Kisianik]

I will come back tomorrow, on the way to work now, there is one more thing left to ask - what BIOS version you have now? The latest? If not do not upgrade till tomorrow, I need to check compatibility.
If you don't know your BIOS version, google CPUID get it, install and check, and post.
I will be back tomorrow.

 

[windowshacker]

Dell Dimension System BIOS, A10

 

[windowshacker]

Also dell dimension can support only up to 570 but im using the 670 pentium 4

How did you choose your new CPU cooler?
Let me summarize your past and present processor thermal parameters
Pentium 520 2.8GHz
Electrical / Thermal parameters
V core ? 1.2V - 1.425V
Minimum/Maximum operating temperature ? 5°C - 67.7°C
Minimum/Maximum power dissipation ? 54.28 Watt (Stop Grant mode) / 100.78 Watt
Thermal Design Power ? 84 Watt

Pentium 670 3.8GHz
Electrical / Thermal parameters
V core ? 1.2V - 1.4V
Minimum/Maximum operating temperature ? 5°C - 70.8°C
Minimum/Maximum power dissipation ? 81.78 Watt (Stop Grant mode) / 148.16 Watt
Thermal Design Power ? 115 Watt

Increase even that small is very serious in PC CPU cooling.

So I need to examine your cooler choice more carefully.

 

[windowshacker]

Wow More HEAT so what can i do

 

[windowshacker]

This is what i have now

this is what i had before

 

[Kisianik]

Do you know part numbers for both items? Or links please...

 

[windowshacker]

i know the part number for the square looking one is called m5051
and the one with copper pipes is W4254

 

[Kisianik]

I am busy now for long talk, will spend a bit more time after weekend, another question, how you come up with idea of changing cooler - as someone said earlier, there is no temp measurement with those processors. And last question, if you know, what is LGA socket you have, basically how you come up with idea that new cooler will mount fine instead of old one.
There is long talk about Dell cooling management, I went through similar situation, hope to explain tomorrow am (my time, lol).

 

[windowshacker]

well when i was using it with the fan was so loud and i checked the heatsink and it was hot then the pc shutdown with and thermal heat error when i was searching for a heat sink i found the W4254 which worked with the dell 8400 for 3.2GHz and faster so i bought it

 

[Kisianik]

Let me first talk a little bit about Dell cooling.
Regarding fan issues in many if not all cheap Dell models. Inspiron, Dimension, Optiplex and Vostro considered cheap models and as such don't have software fan control, meaning that BIOS and motherboard are controlling fan speeds, no matter what program you will try, I tried to, but I could not increase fan speeds, even when CPU was overheating. This is part where I am guessing: original CPUs are very low wattage and low heat producers, so BIOS and MOBO adjusted to for those parameters, when you place much stronger, and therefore more heat producing CPU in, it requires more power and produces more heat, however motherboard doesn't know this and continue to operate as if it is still low heat producing CPU.
In your particular situation you most likely still have original CPU fan, am I correct?

Oh, man, you got me into long explanation

Next reply I will show many important pictures, so every one else can help without looking for this.
