Yes that intel turbo boost really is an abomination. The fact is you might not even be aware that DELL shipped your laptop auto-overclocked, or not realize it has an impact on the durability of the laptop.
You can use capang trick to disable the overclocking (make sure you do that on EVERY power plan setting), or disable it in the BIOS. It should be easy even for people with little experience. Just press the BIOS key (F2 for N5010 I think) when you turn on your laptop, and somewhere you should find the IntelBoost Technology that you should disable.
Overclocking is meant to improve performance, but honestly, it doesn't make much difference (or at least not for the average player). However, you can easily reduce your CPU temp by 10 or 20°C by turning it off.
I remember doing that on a friend's laptop (really good RoG computer with intel t7 and stuff). The computer didn't even need to operate with max graphics on most games, and the temp dropped from 70°C to <50°C. And big bonus : the fan doesn't need to spin as fast, resulting in a much quieter computer (felt like turning off the vacuum cleaner...)
I also have a N5010 and i'd say my problems are much worse.
I do have a cooler and turned off overclocking, but i'm still reaching
>110°C for the GPU
>100°C for the CPU
>80° for the RAM
I opened my laptop recently, and i was very suprise there was almost no dust in it. Only thing i haven't done yet is to replace the thermal paste of the CPU, and use new thermal pads for the GPU. But anyways, I'm afraid one of the GPU capacitors's dead, which could explain why it's running so hot
(And I only need to play 20 mins on XCOM with lowest graphics to reach those temps, then the laptop shuts down)

i have a inspiron 15r n5010 with the same core i5 460m 2.53GHZ. when my dad gave it to me. i cleaned out the fan and air vents but core temp was still giving me temps in the mid to high 80s in C so hot! i found 3 ways to keep the temps down. see results in the bottom
#1 i went and bought some new thermal paste from frys. when i took off the heat sync it was all crusty. so i put some new paste on it. that helped a ton.
#2 i got a cooling pad. currently i have a $10 pad i got at frys. it is a gearhead dual fan pad. just a little one. it does the job tho. i am waiting for frys to get the coolermaster X2 in stalk. that one is a beast. anyway. my 10 dollar one keeps the temps down a tad. i also have a extedned battery that sticks out the bottom. so even without the pad i recommend getting one to help with air flow
#3 one thing that is a blessing and a curse is... intel turbo boost. it is great because it gives you 2.81GHZ when you need it. the bad thing is it makes you cpu HOT! i found a way to disable it. i dont currently unless i am on battery. but its very easy you go into your power plan settings. and set you maximum cpu state at 99% that way it doesnt activate turbo boost. without turbo boost running at full load @2.53GHZ before new thermal paste. i would get max of 75C with the thermal paste it get 68C this is without the cooling pad. now compare those to with turo boost
