Unusually hot CPU readings from my E6300 Core 2 Duo

I know this question has been raised a lot, but I'm not sure what to trust. I'm using a
GIGABYTE GA-965P-DS3 motherboard and as stated previously E6300 Core 2 Duo with the packaging heatsink. At idle temperatures my BIOs was showing a temp reading of 60c, whereas Speedfan was showing 45-50c, and Core Temp was showing 60-63c. I only tested Speefan, but it was showing 75c at maximum capacity. Speedfan was also giving odd reports that the HSF was running at largely different RPMs. These could fluctuate anywhere from +4000 RPMs to -4000 RPMs at any given time. It would sit at 6600 RPMs then shoot up over a course of 5-10 minutes to anywhere from 15,000 to 24,000 RPMs when there was no visible or audible difference in fan speed. Anyway, I know the heatsink is notoriously difficult to properly seat but I'm fairly certain it's seated properly. The only issue I may have is that, when the heatsink was initially applied, I removed it because I couldn't get the computer to POST (realized I was using the unsupported OCZ PC6400 dual channel memory which was causing the problem.) So anyway, I removed the heatsink from partially dry thermal paste, and I dunno if taht would cause an issue or not because I've applied direct pressure to the heatsink with no visible results. When I touched the heatsink, it didn't feel more or less hotter than room temperature, so I can't tell what the case is. Any help would be appreciated, I dunno what to believe at this point.

Okay, thanks. I've been searching around and it seems the issue is probably due to air bubbles trapped in the thermal paste. Does this sound like a valid reason for the issue to be occurring; because that was my initial thought.

Hrm...no. Do you have any Arctic Silver around? If so I'd take the HSF off and clean it with some 91% Isopropyl Alcohol and let it dry for about 10minutes (same with the CPU). Then I'd put the CPU back and apply a small dot of Arctic Silver to the middle of the cpu. I'd make sure to not use more than about the size of a grain of rice. Then smash the heatsink on it and avoid sliding it around if you can help it before attaching it.

I don't have any on me at the moment, but I'm going to get some tomorrow. Where can I pick up 91% Isopropyl Alcohol?

91% Iso should be available just about anywhere. It's not a restricted substance or anything. Look for peroxide, it is always by there.

Okay, is there anything else you'd suggest that I could maybe find around my house? I'm kind of strapped for time and I just want to stabilize my system asap.

Nah...91% is good because it dries fast and doesn't have much water at all in the solution. It cleans better than the 70% stuff. It's available at any drug store.

Alright, I'll definitely see what I can do. Thanks for the replies. If this doesn't turn out to be a thermal paste issue I'll be upset :/ heh.

Before you start reseating the cpu download coretemp, it currently gives the most accurate readings of core 2 duo cpu's, other programs are giving reading that are WAY out.

actually coretemp seems wrong too depending on the motherboard.

Ah he's using a gigabyte mobo. Coretemp corresponds with my own readings on my asus board for reference.

From what I can tell Core Temp was the most accurate because it matched up with the bios cpu temperature reading. I contacted Gigabyte and they said it should be an accurate reading from the bios so I'm gonna go ahead and assume that's the case.
