I'm having this problem and it's driving me crazy 'cos I can't for the life of me work out why it is doing this. My CPU fan for the past 2 years has sat nicely at around 900RPM which is nice and silent. However, I recently modded my PC with a new case and some cold cathodes and LED fans. Now, everytime I turn more than 1 cathode on, the CPU cooler starts going crazy and speeding up and slowing down and it's quite annoying and then it settles down if I turn them back off. What can be creating this issue?
Cheers. Trev.
P.S: PC Specs if they help are:
CPU: Intel Core 2 Duo E6850 3GHz cooled by standard LGA775 third-party fan cooler.
RAM: 3GB Dual Channel DDR-667
PSU: Bestec 350Watt
Motherboard: Asus P5Q
Graphics: ATI Radeon 3650 HD
Others: 1 sound reactive cold cathode, 1 liquid effect cathode, 2 LED cathodes and 3 LED fan. Case also has 3 front backlit LCD Screens.
May seem overkill with the specs for this problem but I guess the more you know the better.
Thanks guys.

EDIT: Narrowed it down to it only happening when the liquid cathode is switched on. It doesn't matter if the others are on or off. Note it is not due to a temperature rise as the problem happens immediately and then stops immediately when turned off.
Thanks again.
