Cpu or Fan problem ???

[Wishmaker77]

I tested my new G751 JY in benchmark firestriker and rest of them , make stress test of Cpu , play alot games with all on ultra and see some problem .... my high temps on Cpu alot times goes on 95 in same time Gpu high temps never goes even on 70 .... alot times i have difrence in temps 30 degrees between Cpu and Gpu ... my fans all time are very silence , so i ask its a problem with Cpu paste or spome trouble with fans , i try check Asus Gpu tweak , but there i see fans on 5800 and when i put make fan on full speed , nothing change so Gpu tweak doesnt work 😞

Wishmaker77, that's because the version that has the Full Fan option is for Optimus laptops - your JY doesn't have Optimus.

If your JY doesn't come with Asus GPU Tweak for Graphics Cards, it may not work. But, you can try, here is the download area specific to the non-Optimus GPU's

Asus GPU Tweak for Graphics Cards, currently at release 2.6.5(.3) for the G750JW/JX/JH and G751JT/JY(??)
http://support.asus.com/download.aspx?SLanguage=en&p=9&m=ASUS%20GPU%20Tweak%20for%20Graphics%20cards...

There are newer versions, up to 2.7.1.8, but they cause problems on G750's, but they might work on the G751JT/JY, if you find the best running version for your JY, please post back here 🙂

The peak temp of 95c for CPU is high, but you really need to monitor your temps in between peaks too, and monitor Thermal Throttling as that is really what the cooling system is trying to avoid. When the CPU thinks it is too hot it Throttle itself and kills performance - you want to avoid that. If you aren't seeing Thermal Throttling, then you aren't running too hot for the CPU.

Asus makes the fan curves for quiet operation, but cool enough for long life and under the thermal throttling limit.

Use a tool like hwinfo64 to log temperature readings, and thermal throttling events, and leave it running in the background. Then you can look at the log file, it's a csv file, with Excel and see how often the peak temperature was reached - more often then not it doesn't happen very often and most of the time you are running well below that even under heavy gaming/application loads.

Before loading the .csv logfile into Excel I use Notepad to read it, and globally replace the semi-colon's with comma's, and save to a different name.

You said you are seeing problems when playing games, what kind of problems?

BTW, the Full Fan option on the Optimus laptops is not to be envied, it is lame to require manual intervention to keep things cool. The non-Optimus laptops keep cool automatically 🙂

Please let us know how the correct Asus GPU tweak works for you, and what the hwinfo logs show for temperature and thermal throttling. 🙂

Ok i install this new version 2.7.1.8 but i dont see any fan speed .... i need some program to checks CPU and GPU fan speed when i stress them 🙂 The bad think i have throltling on cpu i using hwinfo64 .... but averange temps when i start hwinfo64 and put game all on ultra i play 2 hours then i stop and check temps , i have averange on CPU 65-75 , on GPU i have 50-60 , but problem is that highest temps on CPU are 95 and i have thrttling on cores on yes 😞 Gpu never have highest even 75 😞

Wishmaker77, what are you running when it hits 95c? The samples are every 2 minutes by default, how many times did you hit Thermal Throttling? On 1 or more cores?

We don't really have a lot of data yet, if you can post what causes the temps to hit 95c and thermal throttling others can try it - it might just be the way it is, or your cooling system might be just a tad off, we don't really know yet.

Don't worry about it yet.

None of the ROG laptops have any fan control, just the Full Fan option, which is *really* loud, you aren't missing anything 🙂

I have a one question about cpu fan. When the fan turns on it will never stop, is this normal? My temps on idle 37 degrees but cpu fan still working.

Artixz, yes the fan will always be cooling even at idle. I think the fan drops down to 2300 rpm at idle, at least on the G750JH.

The only program I have found that actually reads the CPU Fan speed is AIDA64. It shows it in the Sensors summary, and in the stress testing section there is a Fan speed graph.

Here is my idle fan speed of 2300

[Artixz]

yes. Aida64 shows fan rpm. On idle have 2300, on load 2700 rpm. My rog on idle could be quieter

Artixz, which model Asus ROG laptop do you have?

Do you have the Power Plan set to Balanced? Let the CPU cool down in between loads, set the CPU Min/Max to 0%/100%. That might help keep the fan from spinning up.

And, try setting the CPU voltage offset to reduce power through the CPU, reducing temperature. I have mine set to -45mV for CPU and cache.

Mine idles at 2300rpm, and the ambient noise drowns out the fan, it is inaudible. At full load, the fan runs at 3900rpm - quite audible 🙂

If you have a HDD it might also be adding to the noise, the vibration from spinning conducts through the chassis and might be echoed up from the surface it is sitting on.

ok my fans checking with Aida64 2200/2300 idle , stres 2600/2700 . I make real time test i use riva tuner with hwinfo64 and i think i find why i all time see on hwinfo high 95 on cpu .... testing now on Civilization : beyond Earth .... i start game temps on cpu 60-65 , fps 60+ cpu using 20% , when i choose all and put start , then on 1 s my cpu goes 100% and temps on all cores on 92+ .... game start all cores max 65 , fps 60+ all stable ... so normally i test only hwinfo64 and when i end playing i see this high temps 92+ ... but i think its just 1 sek ....

Wishmaker77, cool, that was what I was hoping, a single spike and then the rest of the time everything is running coolly.

That is why it is good to look at a logfile of the entire run of the test, with a sampling rate often enough to see the dips and peaks in the load / temperature.

Your temps are aok 🙂
