High CPU Temps, Replace heat sink?

Hey guys, this is my first post so I'm not sure if I posted in the right section. Anyways my CPU has been really hot.(50's idle, high 70's Gaming) I tried to repaste the thermal compound but it only helped little. The rest of my computer components are fine, so I suspect its not a airflow problem.

About my computer:

HP Desktop, Pavallion (forgot the actual number), MS-7778 (Jasmine) motherboard, generic coolmaster heatsink.

Do you guys think I should replace my heatsink? How do I find the right one?

Would you post your component list? It sounds like a CPU cooler issue. What is your case and what fans are installed/

It's the HP PAVILLION 500 series case.
AMD A8-6500
8 Gig Memory Stick
2 TB Hard Drive
Radeon 7850 GPU

GPU has its own built in fans.
My CPU heat sink looks like this http://www.splusdirect.com/hp-cooler-master-socket-775-... (not sure if its exactly the same).
I also have a small fan near the end of my computer.

The computer case doesn't appear to have many ports for case fans. Are there any unused fan ports? There isn't much detail online about the case.

To improve the cooling you can try replacing the thermal paste (Arctic Silver is a good one). Use an 1/8 inch drop in the center of the the CPU, and then reinstall the cooler.

The next thing I would try is replacing the case fans and CPU cooler. An alternative to replacing the fans is to move the computer to another (better cooled) case.

To replace the existing fans, it is necessary to measure the fans (there is no fan info in the specs) from edge to edge in mm.

It is also necessary to measure vertically from the motherboard surface to the inside surface of the case side panel for a new CPU cooler.

The temperatures are fine since the computer doesn't reset with its bios temperature limits

It is probably a good idea to get a new case, since you will only have to remount the motherboard once since all the good aftermarket cases have access to the motherboard on top and bottom. It will also allow you to install the evo 212 plus which has a really really tall heatsink.

If you will be buying a new cooler, ask everyone's opinion on the best low profile CPU cooler since there is no way a tall one will fit in the case and you will have to remove the motherboard to change out the heat sink bracket.

I have hp p7-1436s with a cooler master as well. The aluminum fins are usually spread out in a circle. The temperature readings are usually different from the actual temperature since the readings given to the software is different from the actual physical temp. My max temp read by HWMonitor is 80º C so far and it is only early May and I have only had the computer since the end of November.

I tried a different heatsink with the computer case completely open for more air flow and it still gave me these abnormally high temp readings using hwmonitor, I was also turning on my computer for the first time after shutting it down two hours ago.

I came to the conclusion that the issue may be that the temp reading may be off. Maybe all of the models are like that?? Ugh.. I'l make sure to build my computer myself next time.

Thanks for all the great suggestions. You guys are really helpful.

Hold on, it seems that the A8 and A6 series come factory overclocked due to AMD Turbo Core but it is easy to disable Turbo Core using the AMD Catalyst Control Center.

I was able to lower it without going into the BIOS.

Right click on the desktop and select AMD Catalyst Control Center. Look for 'Power' main section and 'CPU Power' subsection. I lowered my max CPU speed by one notch from 3.6 GHz down to 3.2 GHz and it dropped the temperature by 10 degrees Celsius. Even if the readings aren't accurate, lowering the multiplier dramatically lowers the CPU temperature. However lowering it further to 2.8 GHz or 2.4 GHz had no impact on the temperature.

The temperature difference is due to the last .4 GHz or the final x4 increase in the multiplier. Plus it runs really quiet now.

I wished someone had told me about this before I sent my computer into HP and they replaced the PSU which was running really hot with a new one however they had also replaced the CPU as well and they replaced it with a refurbished one and it ran hotter than the one that they had replaced it with.
