Hi! I have a simple question regarding Max TDP:

I have a AMD MoBo 785GX SB 800, currently I have an AMD V140 @ 2.33 GHz Max TDP 25W processor but I´m looking to upgrade to an AMD Phenom II N970 @ 2.2 GHz Quad-Core Max TDP 35W processor...

My Question is this:

Is that 10W difference risky?? Would it work?? Would the processor performance be affected??

Please, Help!!

Thanks in advance!!

In a desktop I'd say no, an extra 10 watts isn't much to worry about.  In a laptop things are.... different.  There's less space which makes it more difficult to dissipate heat.

Whether or not it would still work depends on how robust the cooling for your laptop is, how much the laptop power supply has to spare, and whether or not you would consider an annoying fan buzzing at you most of the time a deal-breaker.

Actually, the fan doesn´t make a big deal of noise, but regarding the power supply I seldom use my laptop´s battery (mostly connected to DC), but not sure if it will provide enough power for the processor to run... the cooling systems consist on a couple of copper looking little pipes that go from the bottom midle section of the laptop (dissipators... maybe?) (where the processor is) and are connected to the fan and another heat dissipator that takes the heat out... the laptop has never got seriously hot, I mean, nothing noticeable at least, I think the cooling system is pretty good and should be able to handle the heat coming from those 10W diff... 

Additionally, I´ve check the AMD site for my MoBo and it states that it should be able to handle ANY of the Phenom, Turion or Athlon...  :S

That's good it doesn't bug you now, but once you drop a chip with a 40% higher TDP in there it might.    I've always been a nutcase about noise though, so maybe that's just me.

Most laptops these days are using heat pipes to help dump heat from one place to another in tight spaces.  If you haven't noticed the cooling setup working overtime, then that's probably a good sign.

True that!!

Yeah, I´m assuming since my MoBo is S1G4 it should be able to handle any kind of Turion or Phenom II processors at any TDP... I´ll go ahead and give it a try!!
