G60JX Forcing GPU Fan? Is it safe?

I've noticed that my Jx has been getting pretty hot while idle at random times (sometimes up to 80C) and once it reaches that type of temperature it will turn on its fans for a few seconds and cool it down to 70C or so then stop.

Is there any way to always force on your GPU fans and if you can is it safe?

Any help?

 

The only danger you will have is putting more strain and wear on the fans.

The temperature you mentioned is perfectly normal for a laptop as for instance after repasting my laptop it runs at 50oC idle gaming 70oC although it can easily push upto 85oc at full load. Which is normal.

If your fan is kicking in at 80oC then its doing its job a GPU and CPU have limits of upto 105oC and normally can easily handle upto 115oC before shutting down.

As you mention its at idle it sounds like you just need to clean the fans out as dust and hair etc can clog them up and this prevents the air escaping. Use some forced air to blow this out of the fans or if you are confident to open the casing on your model (I cant advise on your model) then you can clean out the fans properly.

 

On idle though? That seems a but pushing it at 80C on idle. I would expect those temps after playing a heavy taxing game for a few hours.

 

Sorry I edited before you replied. Recommend cleaning the fans out see above it sounds like the air is not escaping as it should. Its high yes for idle but still within operating limits for a laptop. Do this before thinking about repasting it lowered mine a good 5-6oC before I did.

 

So you're suggesting to open to clear the dust? Hm... never opened a laptop before.

I'm not sure the fans are even on. It seems they are completley turned off until it reaches 80-85C then it turns on (I can hear them) then shuts off after a few minutes as if it pulsates.

Are there any tutorials to open it up and clear dust? I don't want to open it and ruin my laptop.

 

You should be able to feel the air escaping if they are on they may just run at a low RPM and then speed up once the temp reaches the point the BIOS tell its to. Have you elevated the laptop for instance putting it on the flat surface or a laptop cooler?

If you search for a dissassembly guide you should be able to find one but as you said you haven't done this before so canned air should be used first to clear the fans out.

Opening a laptop is always the last option unless you know what your doing.

 

I feel a very slow, calm airflow at the vents on the left. I've always keep it on a flat surface (large hardcover book or a desk) but was thinking about buying a laptop cooler. Do you know any good cheap ones?

Would be shooting air into the vents without disassembling help it?

 

Forced air will spin the fans faster than normal and blow out the dust and crap inside but you need to be gentle as to not damage the fans.

As you can see the interior only has one fan so it sounds as though its working as it should.

I use Zalman but its not cheap you can get one on ebay for cheaper but if your looking for the best Zalman is one of them.

 

Walmart.com: Zalman NC1500-B Black Laptop Cooler Up to 17": Computers

This? Not too expensive.

Are you talking about blowing air into the vent or dissembling then blowing air?

 

Yup thats the one I got mine years ago so it was a lot more its still going and its on around the clock so worth getting.

A blast of air into the fan will cause it to spin faster than normal and force any dust or crap etc out of it but only a blast not constant otherwise it can cause damage to the fan so its best to use a can of forced air and fire it in with short sharp bursts. If you were to open it up you wouldnt need the air because you could just whip the fan and heatsink out and thoughly clean it.

As per the picture though it only has one small fan for the CPU and GPU heatsink so im not really surprised its running quite warm tbh. As long as the fan keeps it below 80oC then you have nothing much to worry about apart from faster wear but as things are suppose to be built to last 7-10 years you will upgrade long before it goes pop.

 

I might actually pick that fan up today or tomorrow, it's pretty cheap and you say it's pretty good. How much does it decrease the temp?

I downloaded a program that measures temp of GPU, CPU etc. and the fan speed. It goes up to 4600RPM when it gets to around 80C then immediately drops to 2600RPM, and while it decreases temp to about 65C it then shoots up again and it goes in kind of a circle.

I'm not sure if the airflow is blocked if it can decrease temp so effectively.

 

Hmm it does sound like either a blocked airflow or that the thermal paste has degraded but even so as i mentioned its a good idea to try and clean out the fans first this is most important. The cooler will only help by elevating the laptop and blowing cold air into the ports underneith you may only notice a few degrees difference.
