Fan speed risks

post #1 of 13
Thread Starter 
I'm about to do some sexytime overclocking on my 8800gt and was wondering whether running the fan at 100%, 24/7 posed any potential risks?

I assume not seeing as they are built to run at 100%, but i thought i'd ask.

Cheers and rep+ to my little helpers.

There shouldn't be, I'm assuming you have the stock heat sink?

Yes, stock with latest card BIOS (if that makes a difference).

You can but they wont last anywhere as long I run mine at about 80% and find that works well enough, you can run it at 100% but the fan will probably only last 6 months not to mention the horrid noise

Well, my case is sound proofed. Maybe i'll just go 70% then

The fan bearings will wear down faster but I don't think it will be too quick. Worst case scenario is you call EVGA and tell them you need a new fan since yours blew out.

But 100% will be really loud. I used to run my 8800GT at 40% idle and 50% load and in this hot weather, it topped out at 63c (was the Rev2 cooler though).

Fan might wear out a little bit faster, but since it is eVGA, they might replace the fan for you.

Just a side note, in the TOS it says you can't say that you are giving reps in when you start a thread. You can give reps, but you can't say that you are going to until the thread is pretty much done and you are thanking people.

It isn't really an issue. XFX are shipping cards that have no fan speed control (they run 100% all the time). But 70-80% should give enough cooling. The card will probably be upgraded before the fan dies.

It will probably run much longer if the fan is set at 90% as lifetime exponentially increases as the fan duty is lower.

While overclocking can't you just modify your bios so the fan speed ramps up earlier as to not allow the card to overheat like the ATI cards?

The fans are rated to run at 100% for a few years non-stop... you'll be fine. Just make sure you register your card with EVGA within the first 30 days. If the fan dies, they will replace the card for you.
Once again...
