Freezing ?
Even with a fan, they're still quite warm.

But ultimately, you appear to be unaware of the class action suite bought by 
the US gov.t against IBM for HDD failures.
And totally oblivious to the vested commercial interests at play here.
This study was not conducted by any kind of academic institution - or 
subject to any kind of peer review.

We have no knowledge of who funded it - or any way of qualifying its 
veracity.
Anyone can claim to have conducted a massive study - and go on to draw 
whatever conclusions they choose.

I would rather believe the evidence of my own experience than some bullshit 
'study' (read : commercial propaganda).
Other than which, any overclocker will tell you that nothing kills a chip 
faster than heat.
Try removing the heatsink from your GPU.
It's common sense, if nothing else.
