Read the first page! there is a picture of someone's setup of using fans to aid circulation
to aid circulation of his cramped cabinet that the ps3 is shoved into, maybe...
please refer to this post if you are trying to understand what I was talking about:

Won't help much at all. The reason is - you still can't properly cool down cpu/gpu chips with that.
Like example in my PC. It has 6 coolers, 2x 140mm, 4x 120mm, + CPU, Power Supply and GPU fans. Also, i have an air conditioner, so i always have not more than +19C in my room.
Yet, when CPU or GPU under heavy load, it get's up to 55C on CPU and 87C on GPU (GTX480 with GF100 chip a.k.a. fermi lol ). While overall temp in my PC case is just about 30 - 33C.
Same for PS3. You'll need to modify the whole cooling system to get some real results, otherwise it'll be a self fooling.
Those things helps a bit only if: it's very hot in your room or you place your PS3 to the limited space (like on Neocodex's pic).
And even if forget about all that. YLOD usually caused by heat/cold cycles, because lead-free solder can't hanle it well and eventually cracks, so CPU/GPU losing conctact with a motherboard and you see a YLOD.
And you can't avoid those cycles unless you will never turn your console off.

If it runs cooler, there will be less expansion, and therefore less fatigue on the solder.
*sigh*
People think it runs cooler, because air from the back and up of PS3 is cooler when you use those things. But chips on the motherboard will be about same temp, it was tested million years ago and not only with PS3.
Even more, all those "devices" may ruin the proper airflow inside the case and because of that cpu/gpu won't be cooled that well = even higher temps for those chips.
I wish it was THAT simple to cool down stuff like that. Just get a bunch of the 3$ coolers and that's it.... =)
