Hi so I purchased a G751JY about a month ago and I'm absolutely loving it but I have a few questions I was hoping someone could answer for me. First off, the G751 has great cooling with the exhaust being in the rear but I love my machine and want to get the most life out of it that I can. So i was thinking of purchasing a cooler for it to rest on to try and get the temperatures lower. With the exhaust being in the back will a cooler actually help lower temps? I don't mind if it's just 1-3 degrees, I just don't want to COMPLETELY waste my money. Also using HWMonitor I've noticed after only a month of use my battery wear level is reading about 4%, that seems pretty fast to me. Is that normal or should I maybe keep a closer eye on it? Also if anyone had any tips as to improving the longevity of my battery for the long run that would be appreciated. Thanks again!

If you don't want to waste money then you shouldn't buy a notebook coolpad. It is quite useless for the G751. There are other ways to reduce the temperatures even more than they are right now. The main solutions are (in this specific order):

1) Do a CPU Undervolt using Intel XTU to about -80mv/-80mv Core/Cache. This won't affect performance.
2) Do a CPU Underclock when 3 or 4 cores are working, also by using Intel XTU. This will affect the performance but it won't be noticeable. x33x33x32x32 should reduce the temps quite a bit while under load.
3) Use NBFC from the link below, but be aware that it is an aftermarket software that will change the way your CPU fan reacts. There haven't been any big issues until now but I advise you to read carefully what I have written in that post.

You can get more information from this post where I have explained for another ROG User https://rog.asus.com/forum/showthread.php?58501-Making-of-quot-Official-NotebookFanControl-G751JY-Profile-quot&p=483592&viewfull=1#post483592.

If you will be tempted to use NBFC then I advise you to read the first 2 posts from that thread.


As for the battery wear, yeah it is quite ok. The fact is that the system doesn't get exact reading of the battery capacity and it varies from day to day. I am also fluctuating between 3 and 4% and I've bought the laptop on 22 December 2014 (almost 3 months by now). And it is like that for more than 1 month. But, in order to better preserve your battery you should follow these rules: https://rog.asus.com/forum/showthread.php?57203-G751JT-need-help-with-battery&p=472094&viewfull=1#post472094

Hope this answers your curiosities :).

After 1.5 years on my G750JH battery, wear level is 8.2%...

And how did you manage to do that :D ? I'm quite curious to know if the things that I have recommended are indeed true or false. I only have a 3 months experience with this one and I cannot have a strong personal background for this subject.

NitroX, nothing special. I leave it plugged in all the time. I only used battery mode a few times. I keep a power adapter at home, work, and in the bag so AC power is always available.

I did run on battery down completely through warnings to shutdown a few times for testing at the beginning of ownership.

The wear level went from 8.2% to 8.5% in 1 day, proving that a watched Battery does go flat ;)

I would love to see someone that uses their G750 predominantly on battery to see how different the wear level is... so far noone has posted that they have a bad battery; it's always a bad charging circuit or a bad power adapter.

These G750 batteries are turning out the be real survivors :)

Oh well, the G75VW was also good at this. After 2.5years it had about 13% Wear level but I did use it with the battery off for a long time. In fact, I'm quite glad that the battery on this one is non-removable because it saves me from doing a useless task like pulling out the battery and insert it again when I needed it. I don't even want to say how many sudden power offs i have experienced on the G75 because of the people at the faculty who didn't ask before pulling out a laptop charger -_- (especially the damn teachers).

Well, I hope that the G751 will perform as good as the G750 with the battery always inside. Though, for your curiosity, I think that people who use the laptop on battery very often will have considerable higher wear levels. I noticed this on the G75 and on this G751 as well. At every 5-10 full battery deplete and recharge the wear level tends to go a bit higher.

NitroX, it's possible the wear level changes up/down over time. I just looked again, and it says 9.7%, funny haha, or funny strange... I think I am going to stop looking. ;)

I have rebooted a couple of times for installs, but haven't unplugged or run on battery after the 8.2% reading above... weird.

Wear level changing weekly. You HAVE to use battery at least once per week to keep it healthy. I have G750JZ for 6 months now and the battery wear is 4%, yesterday was 5% 2 weeks ago 10% and then again 5%. Its changes depends on the battery usage. If you're using it a lot or just here and there. All in all no worries. As long you use it here and there and not completely discharge it (around 10-15% left) you should have it for 4 years without any problems. Don't bother removing it out when you're doing heavy gaming either because it may just do more harm than good. All in all no battery will last 10 years with no wear what so ever, which may change with carbon based batteries but that is still yet to come ;)

navis995, it's an interesting theory, not sure how it applies to my usage and resulting wear level number, I haven't used it on battery at all for months, and not since I first started looking at the wear level again this week.

It's definitely true for me. For example I didn't use the battery for a whole week and wear level was at 10%. The I started using the battery and upon my next inspection I had it on 5%.

Ahh, it was just decalibrated. I'm checking my wear level every day with HWMonitor, and I have been checking the wear level on the G75 for almost 2 years. I have seen how the wear level evolves and yes, there are some changes that occur but they are mostly around 1% . Those readings that you are talking about are just faulty readings due to battery decalibration.

Guys, so today for fun I ran on power until it slept, then charged from amber to green light, and check the reading before/after.

9.7% wear level before I switched to battery, 6.2% now after re-charging.

Make of it what you will :)

Which battery calibration tool do you use NitroX?

No tool. I just made a full discharge/charge cycle once a month or so. The procedure goes like this: Let it full charge to 100%, then discharge the battery to like 10-15% and then fully charge it again. All these steps should be done continously, without breaks while charging/discharging so you will have to pick your time when you are going to do it.

It's pretty much how you've done it. I guess that you have a calibrated battery now :P. You'll know for sure by checking the wear level for a few consecutive days and see if you get again big differences like before. Anything under 2% would be a normal faulty reading that doesn't require calibration.

All in all, battery calibration changes only the readings from the battery because the actual wear level will always be the same for the battery itself. It's just that the sensors sometimes fail to estimate correctly the useful capacity of the battery.

Thanks for all the replies guys very helpful, A couple questions though. The reason I considered additional cooling was because my temperatures are pretty high (Battlefield Hardline Ultra CPU-86c GPU-69c). Now as far as some of your other solutions I've always been under the impression that undervolting can be just as dangerous as overvolting your hardware. How does undervolting affect your hardware? Are these temperatures about normal or should I be concerned? They are quite high but I suppose notebooks are meant to run hot.

I just recently made the jump from primarily using a desktop to now using a notebook so I'm used to far lower temperatures.
