Changed thermal paste and heatsink assembly, CPU still overheating

I have a six year old ASUS i7 computer system. I had overheating issues, and replaced the thermal grease on the SB and CPU heatsink assemblies, the SB is fine, but the CPU overheats still. I added another fan to the case, no go, so replaced the heatsink and fan on CPU, no improvement over the slightly reduced temp after the case fan was added.

I have a couple of questions to ask:

does unused thermal paste go bad in the tube? (My paste could be up to ten years old, though it's been in a well closed syringe type container). Do I need to buy it "fresh" and start over?

I then replaced the heatsink assembly on the CPU. I still have overheating. I read in another thread that reset of the CMOS was necessary after doing these things to finally fix the CPU overheating problem he was having. Do I need to do this?

And if this question is answered elsewhere and I missed it, apologies all 'round!

I personally have never dealt with the CMOS when dealing with overheating issues, so I dont know too much on that specific subject.
Outside of what you already tried (Good to know you have some knowledge, makes my job easier)
The thermal paste could be acting as an inulator at this point, but the SB is working better. So its a bit of a toss up.
The model dosent matter too terribly much, but newer i7s have better thermals than older models, so its easier to tell what is an "acceptable" range. If you are still using the stock intel fan (short, round one) you may wish to use a different aftermarket model.

I did all the usual things, I am about high-intermediate in terms of hardware skills, as this computer is the first prefab I've ever had. (Hence why I'm not familiar with the specs). I used to build my own, from castoff parts :)

checked all fans were working, and dusted entire unit, including the heatsink and all fans.

Added an auxiliary fan, after changing thermal paste and a new heatsink/fangave only 5 degree change. (This was not a souped up model of cooler).

I am using the "relative" method of determining if the temp is too high. It used to sit around 45, it began to overheat to around 70 when using psp or photoshop. When I use other, more undemanding programs it only rises to around 57,.about the max I ever saw it go before this current debacle. I do wonder why what i7 it is would matter, since I don't overclock and I'm using relative temp as opposed to absolute-i'd have to fuss to get that info since the computer has been partially disassembled while I work on it, since a complete cleaning/overhaul would rule out quite a few issues and I was overdue anyway. I just wanted to cover in case what I'd already tried was not correctly done, hence the two questions. I'm pretty good at troubleshooting, so I still have a few more things to try before forking for the aftermarket cooling, or, if that fails, a new CPU and perhaps a new MB while I'm at it :) It's aging.

The HDD, the case, and some fans have all recently been swapped, so I have a pretty nice alienware case and all the other temps are better than I started with. I was having SB overheating but case/fan change and new thermal paste took care of that. The CPU started overheating after all that, I will be checking that I didn't cause this issue, though it didn't happen immediately after, I can't rule that likelihood out.

I wouldn't mind an answer the CMOS question if you can...and if giving you specs would make some sort of difference, I can find them, but would love it if you could explain why, as it isn't intuitive that it should be so.
