    I recently purchased a 13" Macbook Pro with the i7 and 8gb of RAM.

    I run certain games on this machine including World Of Warcraft, I crank up the fans to 6200rpm via SMC Fan Control to prevent the CPU from reaching high temps (up to 100c).

    Will running the fans at 6200rpm for a few hours everyday do any damage?

    Thanks

    The only thing I can see happening is a shorter life on one or both of your fans. Might happen. One other thing I just thought of is dust. What you take out must have first came in. So if your running your fans at that speed all the time your going to find dirt and dust collection allot faster then normal. I'm not sure how much they might be to replace however.

    On kinda the same note I installed SMC Fan Control. I like it.

    It's not necessary and will likely damage your fans if you continue to do this for the long term.

    Damage as in sudden catastrophic failure? NO.

    Shorten fan's life? YES. Will it fail BEFORE u grow tired of this notebook? UNKNOWN. But then fans are relatively ez to replace.

    Expert engineers have spent lots of time calibrating the fans. Let them do their job, I'm sure they know better than you do.

    I don't think it's a good idea to run this machine at 90-105c for long periods of time. I just thought this would be a better solution.

    I'm running the fans at that for about 3 hours a day

    It only takes a few minutes to replace a fan so i will take that over cooler running temps .

    That is also of course if your fan fails after the warranty ends in which case Apple will fix it if within the warranty period .

    I blast my RMBP fans full blast and have on all my other machines never a problem so do not even think twice about it as long as your happier with cooler temps vs worrying about a fan or 2.

    I used to run a bunch of folding computers, many with CPUs that run at 100ºC all day, everyday—never had any issues.

    Switch to UltraFan it`s a far better solution, yes fans will incur greater mechanical wear & tear, however very marginal. What you are more likely to do is pull in more dust into the cooling system and this will degrade it`s efficiency over time depending on your environment. The fans are highly unlikely to suddenly quit, rpm`s may drop and fan noise will be come noticeably different.

    The elevated CPU temp wont in general be an issue, however a high cyclic rate from very hot to cold will in time degrade the electronics up to and including hardware failure, this is systematic of thermal stress/shock which is a frequent killer of electronic`s

    It's perfectly within the operating temperatures of the machine and will additionally shut off automatically before internal components are damaged by heat, in my 10 years of experience with Apple portables I've never seen this happen.

    I would run my Mac around 90C rather than running the fans at 6200 3hours/day.

    That would definitely shorten the life of your fans.
    I would get Apple Care if you are still under warranty.

    buy a cooling pad for $20 and leave the fans alone :)
