Which fan is loud, the CPU fan?

When you say the PC case is not even hot, how are you checking that? Just touching the case doesn't give any indication of the temperature of your actual components, the CPU could be getting extremely hot and the case will still be cool to touch.

Use a program like HWMonitor (its free). Download, install and run the program then after a few seconds once all the information has come up screenshot the full windows and post the screenshot in a reply here.

Are you referring to the power supply fan?
The faster processor is probably using more wattage and is putting more of a load on the power supply and making the fan run faster to keep it cool.

It looks like you've installed the fastest Intel Pentium 4 processor that the Dell Dimension 4700 desktop supports.
It has 4 slots and supports up to 4 GB of RAM.
Besides upgrading the processor, did you add more RAM?
That would be the fastest and safest way to get more speed in that desktop.

It appears to come with a 305 watt power supply.

Yes I have 4Gb of ram and it's the CPU fan running loud it's using the stock heat sink for the 2.8GHz

I'm not an expert in processor(CPU) upgrades, but it's my guess the 3.8 GHz is putting out more heat than the 2.8 GHz was putting out and is causing the heatsink fan to run faster.

You probably need a heatsink upgrade before that one wears out from the overspinning.

What heat sink I should get that fits the dell 4700 I checked the heat sink and it supports up to 3.2Ghz which is not working well with my 3.80Ghz CPU

I did the same thing ,upgraded from a 2.8 to a 3.8 and my cpu fan (the exhaust fan i call it) speeds up when i play a on line army game and when i get done and close out the game ,..the fan will slow down..a lot...so i figured the fan is having to cool the processor ,of course its going to be a lot hotter than the 2.8. I took a 12 VDC fan and mounted it over the cooling shroud ...it is quieter and hooked to a CD rom power source but dont do this if you haven't before.Yes that processor will get hotter ...it is a whole ghz higher than the original

Can you send me a picture of the inside of your 4700 and can you tell me how did you hook the fan which cable.
