I have a 4 month old Mesh Elite Express with an ASUS P5N-E SLI nForce 650i SLI(C55)- Core 2 Duo/Quad-Core - ATX motherboard, I've replaced the original Core 2 Duo E6600 dual core processor with a QX6700 Core 2 Extreme Quad. My research has shown no changes required to BIOS. All is working fine but the fan appears to be operating at full speed (it's constant), and it's very noisy - it is the stock Intel fan. Is this a simple case of getting a quieter fan (in which case which would be best) or should I be checking out something else first? I don't have a CPU temperature monitor/fan speed control - I did try one of the free downloads recommended in this forum but it didn't work. Any advice much appreciated!
You'll be hard pushed to find a fan to replace the stock one as it's a non-standard fitting.
Quiet PC have a good range of heatsink/fans click here
I've got the Scythe Andy Samurai but the Thermalright Ultra's get good reviews. For either of them you'll need quite a bit of space for them to fit. The 120mm fans run slower and quieter than smaller ones.
Also in addition to the above post by Marg7 setting Speedstep to enabled in the BIOS allows the CPU to cooler when not under load.
Sorted - the BIOS has a CPU fan control that was disabled (why - wouldn't enabled have been a better default?), anyway speed is down from 4200 to 2900 rpm and there's much less noise with temp at 45C. Still not the quietest fan but we'll see how it goes. The ASUS programs aren't loaded and Mesh didn't supply the CD, I'll get these from ASUS, including Probe. Thanks again for the pointers.
