Fan on VRMs no difference?

[Mr_Random_Guy]

So in SpeedFan I was getting readings of temp 1 being 40 Celcius, temp 2 being 55 Celcius and Temp 3 being 76 Celcius under prime95.

So assuming one of the temps was for my VRMs I put a small amd stock fan directly on top and...

exactly the same temps. Others on the internet who have done the exact same thing are seeing huge temp drops.

So what does this mean? Are those temps not for my VRMs but possibly my northbridge/southbridge? There are no other temp readings for the mobo.

 

Thanks in advance

i would guess socket temps or similar

Take a picture of where you're pointing the fan at, please.

yes those are likely not your VRM temps because those should read at least 120c and probably even more considering youre pushing an overclock on an AMD FX chip on a very cheap 4 phase motherboard...VRM are meant to run hot though and 100c or 110c is pretty common for AM3+

You should probably tone down your overclock though before you break something...is the CPU throttling under load?

@TheRandomness The fan is zip tied on so don't want to take it off but I can tell you its definitely on the mosfets heatsink

@i_build_nanosuits The CPU doesn't throttle and maxes at 55 C, and is my mobo likely to break?

Well, they're not meant to run hot, but they can do so. 90 celsius is around the max safe acceptable temp for VRMs of any kind

Was just checking

I'll just leave the fan on then even if I can't see the actual temp drops.

@i_build_nanosuits Dropped the voltage to 1.38, falling to 1.33 under load compared to the 1.4v at load i was pushing earlier. Is that much safer?

That board has no vrm sensors or northbridge sensor, most AM3+ do not have either of those things as a matter of fact. What type of clockspeed are you trying to push, i would stay under 4.4 ghz or 4.3 ghz if voltage is not too high, obviously a 4+1 phase board is not meant for overclocking but that one is capable of 140-150w and has a thermal shutdown for the vrms, so it should shut itself off before killing itself, just dont push it too hard. I ran with a 6300 at 4.3ghz for a year or so and it never gave me any problems though voltage was only about 1.3125.

yes that should be within the safe operation range for this CPU on that motherboard.
