Hey guys a couple of questions regarding TX-2 DV6700 and ENVY 15

Hey guys, I haven't posted here in along time and I am starting to feel the forum warmth again (or its the excess heat in my tx-2 ). Anyway I have a couple of questions.
FIRST:
For all the tx-2 users what kind of temps do you guys get? I have been looking around and I am seeing people claim that they get 110c heat ? I received the notebook a couple days ago and I did the PENNY between gpu and heatsinc (Not with a penny) and I removed the silicon/rubber pad that was between them. I also cleaned the original thermal paste and put Arctic Silver 5, I am still breaking it in but my temps range from 60c on idle and 85 on 100 % cpu usage... Is that ok and if its not what else can I do? (PS i also cleaned the vents DUUH )
SECOND:
Sorry if its a dumb question, but I could not find the answer anywhere. I want to buy this: to put it in my DV6700 or the tx-2 but I dont know if it will work since its for IBMs and I have not found anyone selling something like it for HPs or any other brand. So anyone think it will work? Please submit anything you think. I am willing to get it even if I need to make some mods.
THIRD:
I am gonna receive the ENVY 15 soon and I want to know if its worth it to get it with the two 160 gb ssd drives instead of the two 500gb 7200rpm drives? The price difference is around $100 and I have already paid for the rest of the laptop but I dont know if I should get the ssd drives? and If I do I would probably use one of them for the notebook (windows and installed programs) and then I would buy an external enclosure(for the second ssd drive) and a 500 gb drive(and put it in the second hdd slot) for movies and music so that would be another $100 dollars. So is it worth it to do the upgrade for a total of $200? Also will the second ssd work fast in a hard drive enclosure or will it slow down drastically? And anyone know any cool mods for the envy 15?

THANKS EVERYONE

 

I know that most sites say that the ultrabay works with IBM only but they are book-worms... I am looking for more of an outside the box thinking/modding/playing Also with normal use I get closer to 70c on the tx2, and sorry I forgot to say that its the tx-2 1275 DX with the Turion RM-74, the only upgrade it has is a 500gb 7200 Seagate HDD. Will the temps drop if I get win 7(since it has lower CPU demands/usage) and if they will, how much?
