Hi guys, long time had no trouble till now. Need your professional help please! The fan on my CPU suddenly starts roaring when I do a few things on the pc. When I'm downloading & unzipping files, when I look at AVI files on Media Player, or when Im looking at FLASH films on the internet. It sometimes fires up too strong when I restart PC from 'Standby'. Ive just ordered some cleaner & paste for the CPU. A friend, who is very PC literate, says to clean the CPU take it out and clean all the fins and take the old paste off and recover.
Now I'm not saying I don't trust his synopsis of the situation, just looking for a 2nd opinion before I fiddle with PC. Have been given info how to do this.
Is there anything else before I decimate my PC that you can think of to help?
Have run Anti-Virus and Anti-Spyware and 'nothing'.
Look forward to hearing from you techno guys out there. :thumbsup:

IMO...fan noise may be an indicator of nothing more than a fan bearing failing.

How about some temperature data to validate some premises?

How do I get the data for you Louis? I'm not techno minded and am a little old to learn now, proper 'Silver Surfer'. Wher do I look, in Task Manager?

Speedfan can collect that data for you. There may be other applications, but this is the one I use.

Thanks Animal, downloaded the link you sent and installed 'Speedfan 4.40'. Readings show as follows:
GPU: 63C, HDO: 43C, HD5:41C, CORE: 57C.
Fan speeds show:
Ambient:0C, Ambient: 38C, Remote: 0C, CPU: 59C.
Is this the info you were asking for hamluis?
Look forward to your answers guys. CIAO!

Good info, thanks :thumbsup:.

Your core temp (CPU temp) may be approaching the upper limit, depends upon the CPU involved. In any case, 57 Celsius is deemed to be on the high side for a CPU temperature, if not necessarily overheating the processor/system. As a point of comparison...my current temps on this system are 39 and 37 (dual-core). The highest CPU temp I've ever seen on any of my systems was upper 50s on a system where the fan had become disabled.

In such a case, the fan should be working harder than normally, since the temp is approaching the (projected) CPU upper limit.

Appears to me that your friend's suggestion was a sound one :flowers:.

Worth reading, IMO: http://www.hardwaresecrets.com/article/143. I have to disagree with a comment made at the link about Motherboard Monitor being efficient as a means of measuring temps...I found it to be very unreliable during the period that I played with it. IMO, the easisest/best way is to check in the BIOS (also mentioned as a method).

Hi again Hamluis. Took the HSF off the CPU, as I did I noticed one of the 'leg supports' was broken at the base, where it screws in. I think the contact was broken and air getting in so not enough cooling down. Ive bought some 'Isopropyl 'cleaner and an 'Arctic Silver' paste. Followed the instructions, mended the broken 'leg' so full contact is achieved, and, Hey! Presto, quiet as a mouse. Tried all the things that set it off revving away and nothing, good as when I bought it, or near as damn it. If the 'leg' breaks again, can you buy the CPU fan only? The 'legs' measure 90mm x 90mm square to centres of screws.
Thanks for your help guys, invaluable service. CIAO!!
The CPU is not reading anything now in 'Speedfan 4.40', got a green tick alongside it. The GPU has a flame icon and reading, 63C. The Core has a flame icon too and reads, 59C.

Replace the heatsink/fan combo.

Be sure to buy the appropriate combination that matches your CPU.

Hamluis, how do i check which heatsink combo is the correct one for my pc? Looked on eBay and there are many. Do I check the fan itself for reference? I really am useless with pc techno stuff my friend. CIAO!!

You need a heatsink fan combo that properly fits your CPU.

Start/Run...type msinfo32 and hit Enter.

Post what is listed for

System Manufacturer

System Model

Processor

Louis

FWIW: I suggest not buying computer parts off eBay.

Pavilion Media Center 7210UK Specs

The key item: Socket 775 processor.

So you need to make sure that you get a combination that fits Socket 775 CPUs or Pentium IV processors.

Since you are replacing the heatsink you should think about getting some Arctic Silver 5.
