Second Cpu fan shorten first cpu life span?

[DemonicHeart]

 a friend of mine told me that if the second cpu fan is as fast as the first cpu fan it will put strain on the first fan and shorten the life span.. is that tru?

[stealth80]

err id say its pretty negligible 

[comefightme]

Doesn't make any sense

[Guest]

Ehhh, no. Sounds like some myth.

Those fans don't even nearly have enough static pressure to influence eachother on that distance or with so much oppertunity to leak or pull air elsewhere. It's not a turbine or something.

If it is as fast it is unlikely to make a difference unless there is a very large delta between the pressure rating of the fans. Even then it is doubtful to have any real effect depending on the distance between the two.

 

Now, if one fan is faster than the other by a considerable amount (strapping a delta next to a low voltage NF-F12 for example) you're going to kill the fan on the receiving end.

 

If you're matching fans up in a push-pull configuration it is always best to match the fans, both with model and tuning profile.

no

[Dapolish]

Nope, thy should never have trouble with such tales, do not listen to such bards that work as fools!

The 120mm fan that is near my gpu, will it put strain on my gpu fan blades in any way??

No, you're fine.

[DemonicHeart]

thanks. i was worried whole day thinking my gpu fan blades will die

lol the distance between the two and the physical space would make it impossible to have any impact, you're doing more good than harm with that configuration (feeding the GPU air).

 

If you had some ridiculous fan (Delta's) slammed up directly against the card you could have some problems :lol:

Thanks.. because when i added the 120mm fan near the gpu i actually got cooler gpu temps by 10-12c

Assuming the faster fan isn't literally a leaf blower, this better not kill the slower fan.

Delta's are leafblowers

Warning to headphone users.

please go tell your friend he/she is a idiot.

Haha yes that fan is nuts. It isn't a computer fan though, it's a 48 volt industrial ventilation fan so I think it doesn't really count towards this question. I've had much bigger fans than that, but engine test cell blowers don't fit in computer cases

Delta computer fans are on par with other computer fans for CFM (though not always on par with volume). The only time you're going to kill a (reasonably built, $1 ebay fans need not apply) fan is by stacking it with something an order of magnitude bigger. Within the mismatch of various computer fans you'll be fine.
