As I mentioned earlier, the CPU will be throttled to protect it from overheating. The things to check in your laptop are that all fans are working, and the air passages are free of dust and lint. With some laptops this can be as easy as blowing them out with air, others need to be opened up to adequately clean them out. Beyond that, dried out or improperly applied heat transfer paste or pads can keep the heat from transferring adequately from the CPU to the heat sink in the laptop. That would require disassembly and replacement of the paste or pad, and proper reassembly to get the CPU in the correct contact with the heat sink. These also apply to desktop cooling issues, laptops just have smaller fans, cooling passages and the like and are more easily blocked up.
Cooling of laptops is helped by raising them a bit off the surface they are resting on so air can also flow under them. If not using a stand, a couple bottle caps are enough to raise the laptop up. Most laptops are designed with adequate cooling to run at near maximum without problems, but maintenance is needed to keep that way.

This. My laptop is running a C2D T7600 (2.33 GHz) and usually does around 2000 PPD; sometimes down towards 1500, sometimes up towards 3000. It depends on the WU, of course. The GPU in it can't fold at all, so I just run the CPU full blast 24/7.
As for heat issues, undervolting the CPU can help significantly with that. I use
RMClock on my laptop with good results. Unfortunately it doesn't work with newer hardware, but a Core 2 system has a good shot at working.

Anyone have any clue what is going on here?
Could be that some other part besides CPU is getting too hot. I've seen that happen with one (old) laptop of mine. CPU temps weren't that bad, but just about everything else was approaching meltdown during extended periods of heavy use. Whatever thermal protection feature it was, throttling the chipset/iGPU/motherboard when one of those got too hot, also throttled the CPU clock.
That laptop simply didn't have enough thermal headroom to run at advertised (stock) speeds for extended periods. Checking out the insides of that thingy was something approaching an Otto moment for me -
"huh...huh...ok...ok...DISAPPOINTED!".
But I digress. Besides Core Temp, see if other utilities such as
GPU-Z and
Speccy can provide some further insight about temperatures. Also, you might be able to even adjust fan speed(s) with
Speedfan.
Whichever program(s) you use, I'd recommend taking the various readings with a grain of salt. Compare the temperature readings between programs and see what happens to them under load and idle. Be
especially careful if you start overriding fan speeds with Speedfan, and monitor temperatures and fan speeds under various loads to see what is going on. Speedfan might interfere with some other method of fan RPM control, possibly with disastrous results.

Since switching to the most updated version of the client, my ppd has dropped from a typical reading of 300-400 to much lower. Right now I am getting 120 ppd but sometimes see as low as 40 ppd. I fold 23 x 7. I dont kno wif the client report is accurate or not. Some WU takes me 6-7 days to complete.

Reconfirm that the slider is set to "Full" and the power savings features are set for maximum performance.
Post the log of the new client.

Slider is set to full, no power saving features are engaged.
The problem is is that my CPUT is being throttled down, according to Core Temp. If I read this right, I am typically folding at 0.8 ghz, not the full 2.4 that my Core2Duo should have. I never had Core Temp installed during my folding time with the old client so I am not able to compare old client vs new with regards to CPU speed.
PPD now shows 600 but I am re-starting my folding after the morning commute. After 20 mins or so temps are at 100 C and CPU throttles down to 50 or 60 ppd. I have no idea why my CPU throttles down to 0.8 ghz. Core temps are at 50C then. Much too low.

With fah set to full, that's about as much as we can do to optimize the fah settings. Why the laptop is using power saving modes is something you'll have to research with the manufacturer.

It's not power saving mode, it's thermal heat protection mode. My CPU throttles down once core temps hit 95 C. I can watch it happen. Once 95 C is hit, the CPU throttles down to 0.7 ghz and stays there forever.

Confirm that the laptop's fan kicks in well before you get to 100C and that the dust-filled twisty maze of little passages have been recently cleaned out. It might also be time for a fresh drop of your favorite brand of silver thermal compound.
When things get that hot, the only way your computer can protect itself from damage is to shut down the processor.

Yes, the fan is going full power long before thermal throttling kicks in. I have taken apart my laptop looking for potential hinderances to air flow but found nothing. I will repeat this again this weekend. I have no idea what your last comment about silver thermal compound means.

That is a hint that you may have to replace the heat transfer compound or heat transfer pad between the CPU in your laptop and the heat sink. It is an oblique comment to the brand name of a popular heat transfer compound.

My friend had a laptop a few years ago that had a bad heatpipe. It had apparently leaked out the fluid inside of it at one point. It was running at 90+ C, but the opposite end from the CPU was cool. Right above the CPU it was burning hot. He bought a replacement on eBay and it dropped temperatures below 60 C.
If you've taken apart the laptop, it should be easy to replace that if needed.
This is the thermal paste I'm using on mine. With the CPU undervolted to 1.1375v, it usually runs in the low-mid 60s C under full load, fan on low-medium speed. It never drops from 2.33 GHz.

A bad heatpipe is a rare failure mode, Thermal paste failure is common for it ages till eventually it becomes just an heat insulator. Also, periodic cleaning with a can of compressed air may significantly help for dust and debris (typically hair) accumulation can significantly harm the efficiency of a cooling system.

True, but it's another thing to check if the laptop is already opened up (although it'll have to be on as well). So far, that laptop was the only one I've seen with that problem.
