GA-E350N-USB3 Temps

[Doosh]

Hi,

Just wondering if anyone else is using this board and what temps they are seeing? I must admit I'm finding it hard to find an accurate reading because all the well known bits of monitoring software are giving different results.

The only common ground is they're all reading higher than I'd like, with no case fan and just the standard heatsink and fan core temp is showing a max of 83 degrees *C under load with an idle of around 53. With a 120mm fan above the heat sink I see temps of 75 under load and idle at 46, but it's far too noisy for a HTPC.

Any ideas? case is well ventilated with lots of free space.

Hi and welcome to the Giabyte forum.

The only way to measure temperture accurately is with a meter. All these board sensors are ok but you never know which ones are correct or way out. Then there is the added problem of how the utility reads them and reports them. Generally I find that RealTemp is one of the more accurate programs.

I can only suggest that you check the heatsink is firmly fixed with the correct amount of paste(too much is as bad as too little) and that the fans are all blowing in one direction to give you a good airflow through the case. If necessary you could always use a bigger slower speed fan as that would be much quieter.

Hi,

Thanks for the reply. I have a slow speed 140mm fan on order but it might be a struggle to fit into a HTPC case. It doesn't really help that there is no fan speed control available via the BIOS, the 80mm fan I have has been controlled via it's supplied voltage adaptors but the ideal sound level is in between two, sods law!

It's fine until it's been hot once, then it stays fairly warm no matter what the load, as another example of varying readings Easytune 6 states CPU temp currently at 33 where as core temp shows 45.

I must admit that the ASUS board with the impressive heat pipe heat sink is looking attractive at the minute, shame it's unavailable in the UK at present.

You could always try something like this variable fan controller from Zalman:

Great minds!

I've got one coming with the fan!

[Dark Mantis]

Ideal. They work very well as I used to use two of them before I upgraded to a six channel Lamptron Fan Controller. For the price of them I don't think you can go wrong.

I think something has to be wrong. Maybe the heatsink doesn't have proper contact with the APU?

I mean, this thing has laughable power consumption and according to this review:

http://www.hitechlegion.com/reviews/motherboards/8872-gigabyte-gae350nusb3-motherboard-review?start=18

it should be about 50 degrees under load. The only normal explanation would be high ambient temps.

Or maybe a lack of cooling in the case.

Like I say, it all depends which reading you go with- according to Easytune it idles at 35 degrees and is around 60-65 degrees under load, this is with a 120mm fan sat right over the top of the heatsink. I'd be quite happy with those figures if any of the other temp monitoring programs gave similar figures, unfortunately they don't.

I'm guessing "CPU temp" is taken from the board somewhere, which would explain why it was a good deal less than the actual "core temps" - which of the two is the more important? I think AMD state 90 degrees as the max, which before the 120mm fan was installed I was getting close to with "core temps".

It is slightly overclocked to just over 1.7ghz but I was already having the same temperature issues before this, changing it makes no difference.

PS - From a quick google search I'm not the only one to comment on the AMD M1 temps so I don't think it is a specific problem to my board.

[Doosh]

Well it's gone the other way now, the 140mm fan is deadly quiet but it's not providing anywhere near enough cooling, that's 3 different fans I've tried this week alone and I'm still no closer to solving it.

I'm wondering if it's worth trying a different 40mm fan that is attached to the heatsink, one with more airflow? it would be nice if I could find the figures for the stock fan so I have something to work from.

[Dark Mantis]

If you want a quiet but very efficient fan the best ones are Scythe Gentle Typhoons. They don't do a 140mm only 120mm but if that would do they come in two flavours 1450rpm and 1850rpm. I would think for your application the lower speed one would be ample. see here:

Ok thanks for the link, another to consider.

I've gone an opened another can of worms now - all the fans so far have been flush up against the case vent holes, I've just re-installed the Noctua 80mm fan so it hangs down from the top of the case by a good inch or more and now it's completely silent. It's not running flat out because for some reason the little fan controller doesn't let it (1500rpm instead of 1800rpm) just off to do some load tests.

I wonder if my noise problems were down to the fan being flush up to the vent and it was suction noise I was getting.

[Dark Mantis]

Maybe or it could have been vibrations travelling through the chassis when it was bolted down tight.

The fact that it's overclocked explains a bit. Cooling on these boards is close to it's limits with stock clocks, so it's best to get some better cooling if you want to overclock.

AMD generally refers to CPU temp as the more important. The difference between the 2, in your case, seems to be a little over the top, though.

Some fans don't like being flush against the vents ( when it's the intake side that's close ) and may cause some serious noise in such a position. The fans that DM mentioned are a prime example of this and gave me a headache or two when mounting them. You can check this easily by unscrewing the fan and holding it in your hand at different distances from the vent.

[Doosh]

Thanks, I'm now certain the noise was due to them being so close to the vent. I've still ordered one of the Scythe fans though as I can't help but tinker 

If the "CPU" temp is the more important one this reduces the headache somewhat as this temp is always about 15 degrees lower than the actual core temp and never goes above 65 degrees even when overclocked, in fact right now I'm multi tasking and it's sat at 32 degrees.

Thanks for the help with this, I thought there might be more users of this chip/APU and board though seeing as what it's capable of compared to the Atom/ION equivalent.
