Safe to run Phenom 2 1055T stock fan at 4000RPMs?

So for some reason or another, after some small bios changes, my CPU fan is hitting around 4000rpm while doing some heavy gaming.

Wondering if this is safe, or if its necessary to drop it? I plan on replacing the HSF soon anyway, so as long as it'll last me another month or so?

Smaller fans often hit high RPMs, but that does seem a little much. Honestly if I were to have a 1055T, I'd buy a third-party cooler anyway. What are your temps idle and gaming?

Well I see all over the place people saying they hit 4000-7000rpms with the stock fan.

But uhh.. I am at 35c idle 43c-ish gaming. I hit 53c in intel burn test.

Those are fine temps.

OVER NINE THOU- oh wait.. you said 7000 ;) .

Well that's still high.. My current CPU fans are running at 1200 and 900 but they're 120mm so I guess it's all relative. 7000RPM is insane on any fan though, I've never seen a PC fan go that fast :o .

If you're only at in the 30's at idle and mid 40's when gaming then I wouldn't bother with a third-party cooler or anything.

It depends on the size of the fan, also a hint - using an intel burn test with an AMD cpu probably won't give the most accurate results.

Check first if those temps are true. I have a 1055t too, and the core temps that most of the programs show are wrong. Install HWMonitor and check cputin temp. It should be ~15°C higher than the core one.

Thanks for the tip, but with the amount I stress out about this stuff, there's probably nothing you could tell me that I don't know.
I was going off of chip temp, not core temp. Core temp is on average 10c lower, as it should be with how botched the Thubans are.

Also, HWMonitor has no cputin temp for me. It comes up as TMPIN1

What in the world are you talking about? Do you even know what the Intel burn test it? And how in the world would it not give accurate results. That post you just made is possibly the dumbest thing I have seen on these forums in ages.

Bob there is right... Using an intel burn test with an AMD CPU won`t give "the most" accurate results.
I actually did that today, just a few hours ago before I even found this thread.. I tested a 1055t chip... I set it up for 10 passes but it finished after 3 with no errors... but I didn`t believe it.. So I used Prime95... and it failed after 9 min.
