I currently have an AMD 1800+ non overclock and it idles at 44c. I would like to start overclocking, but with my Volcano5 heatsink, and the 44c idle, its not going to happen. So anyway, if anyone that can recommend and pretty decent heatsink/fan, please post. Ill only overclock about 100mhz. It also has to be cheap, I cant afford much right now. Any help would be great.

yeah i would bet you could OC it only 100 Mhz without a new HSF, but if you want a pretty cheap one that's pretty good, i like the thermaltake volcano 7+ b/c if you don't want noise there's a speed controller, if you don't mind noise you can choose the medium or high settings. around $30 if you look at www.pricewatch.com
well 30 seems like kinda alot for my budget right now...im saving for a new mobo and radeon 9000. right now with my volcano5 I get idle at 48c with the max overclock I can do at the moment. Since my pos mobo bios blocks the core fsb, I have to change it in windows. The max I can change it in there is to 140. Thats less than a 100mhz jump. If I go to 150, then my PCI frequency changed too much or something and its an instant crash. I want the new hsf for when i get a new mobo that actually is overclockable.
BTW, im wondering.. Why are the case fans so small? My small table fan, which pushes a hell of alot more air, has about the same noise level as my current pc ones. Why cant they lower the rpm, but make bigger fins? I dont understand it...Anyway any sub $20 decent performing hsf anyone knows?
I keep my side panel off. Some people say its worse blah blah etc, but my temp is lower with it off, due to me only have 1 case fan and 1 psu fan. I dont know about the dremel... My case temps seem really good now.. To prove that, even when I have a huge fan blowing cold air in, my CPU temp only changes 2 or 3 degrees. And thats with my small oc. My board temp does change quite a bit more, but in not really concerned with that.

There's a fair bit of difference between Alternating Current, and Direct Current.
Edison and Tesla had a little spat over this. If it had been conducted with Tesla's method, they would have shipped Edison out in a body bag.
So, to make a long story semi-short, AC can pull much more power per ampere than DC can.
That's why those nappy little Radio Smack 120V 120mm case fans are so quiet. And that's why you can use a rheostat on them, without generating 1/10 the thermal radiation that a equivalent potentiometer will.
God damn magnetic fields. Thats the problem with the world today...

Actually, the Volcano 5 isn't a terrible heatsink. It's only 2 degrees warmer than the Volcano 6Cu+ which has the advantage of a copper insert and a noisy Delta fan. For only 100 Mhz of overclocking you are probably fine with what you have.
You can swap in a more powerful fan and it will cool better.
I have a very similar heatsink, a <A HREF="http://www.nexfan.com/29/248.htm?692" target="_new">Galaxy GC21</A>, which actually is the same exact heatsink but with a different, 6-tab clip. My Tbird 1.0 at 1.5 Ghz it idled at 43 degrees with peaks around 50 with the stock fan. I swapped in a Delta fan and lowered those numbers to 39 and 47. Got tired of the noise (a lot of noise) and replaced the fan with a <A HREF="http://www.nexfan.com/43/425.htm?692" target="_new">Y.S.Tech TMD 70mm fan(5800 RPM model)</A>. Temps are back up to 43 and 49 but this fan is so much quieter (despite the noise numbers) than both previous fans.
I had to do a slight mod to make make a 70 mm fan fit. Not really a mod, I just rotated the fan about 10 degrees clockwise and used two extra long screws, which wedge between fins on the heatsink, to hold it.
By the way, don't plug a TMD fan into a motherboard fan header. I heard there is a 0.8 amp of inrush current which can burnout the header. My fan is powered directly from the power supply. Use a 4-pin to 3-pin (w/ RPM Sensor) fan wiring adapter
