my fan keeps spinning full blast when i try to open profile web pages with standard graphics. then it slows down for 30 seconds then speeds back up again. during its peak spin my pc slows down (almost to a freeze) till the fan slows a bit and cpu is cooled a bit. is there anyway i can combat this. i already have dual fans in the psu and a single fan on the heatsink. i don't have a graphics card as i dont use this pc for gaming.
Well, it's doing what it is supposed to do, speed up to provide more cooling when the temp rises on the CPU. You may need to install another fan for fresh air intake on your case. You can remove the side cover and run it that way to see if the problem is minimized. If it is, you should add another fan (probably on the mount on the side cover) blowing cool air on the motherboard.
Also, adding a graphics card would allow the CPU to run cooler since it wouldn't have to process the graphics for the onboard graphics chip.
