Who can incress speed fan for Acer Aspire 4520G

Recommended Posts

Unlimited

When I start it. I check temperature. OH MY GODDDD I have 70 degree Celsius for GPU and 55 degree Celsius for CPU T-T

Who can help me???

Plzzzzzzzzzzzzz

I don't think that there is any readily available software that can do this. 70C and 55C isn't bad either.

I ues Everest read it but when temperature up to 80 degree Celsius. It stop working.

It shouldn't do that. 90C should be the cutoff point (for GPU) temps. 80C is cool by any standards. It may be your BIOS but i am not absolutely sure.

oh I want to incress speed fan. I thing 65-75 C It better for GPU. Geforce 8400 have heat cycle. When use it long time will over heat and stop working.

All Nvidia G84 and G86s are bad

Comment No word on MCPs yet

THE BURNING QUESTION on everyone's mind is what Nvidia parts are failing in the field? No GT200 jokes here, NV personnel are still quite sensitive about that, but our moles have told us about the bum GPUs.

The short story is that all the G84 and G86 parts are bad. Period. No exceptions. All of them, mobile and desktop, use the exact same ASIC, so expect them to go south in inordinate numbers as well. There are caveats however, and we will detail those in a bit.

Both of these ASICs have a rather terminal problem with unnamed substrate or bumping material, and it is heat related. If you ask Nvidia officially, you will get no reason why this happened, and no list of parts affected, we tried. Unofficially, they will blame everyone under the sun, and trash their suppliers in very colourful language.

The press is totally stonewalled, but analysts are quite another story. If you call up with Wall Street credentials, they will tell you what is going on, but unfortunately it doesn't seem to be entirely accurate. What analysts tell me they were officially told is that it is a specific batch of parts that only HP got.

The official story is that it was a batch of end-of-life parts that used a different bonding/substrate process for only that batch. Once again, the trusty INQUIRER bulls*** detectors went off so loudly that the phone almost vibrated out of my hand. More than enough people tell us both the G84 and G86 use the same ASIC across the board, and no changes were made during their lives.

When the process engineers pinged by the INQ picked themselves off the floor from laughing, they politely said that there is about zero chance that NV would change the assembly process or material set for a batch, much less an EOL part.

On the less technical side, multiple analysts also told us that NV specifically told them that this problem is confined only to HP. I wonder why Dell is having failures in huge numbers for their XPS lines and replacing them with ATI parts? Why is Asus having similar problems? Go check the message boards, any notebooks that came with G84s and G86s have boards filled with dead machine problems. Most of these, especially on the NV forums are being quashed and removed by admins, so act quickly and take screenshots of your posts.

Basically, NV seems to have told each analyst a highly personalised version of the story, and stonewalls everyone else who asks. Why? The magnitude of the problem is huge. If Dell and HP hold their feet to the fire, anyone want to bet that $200 million won't cover it? This has all the hallmarks of things the SEC used to investigate in a time before government was purchasable.

The other problem is the long tail. Failures occur due to heat cycling, cold -> hot -> cold for the non-engineers out there. If you remember, we said all G84s and G86s are affected, and all are the same ASIC, so why aren't the desktop parts dying? They are, you are just low enough on the bell curve that you don't see it in number that set off alarm bells publicly yet.

Laptops get turned on and off many times in a day, and due to the power management, throttle down much more than desktops. This has them going through the heat cycle multiple times in a day, whereas desktops typically get turned on and off once a day, sometimes left on for weeks at a time. Failures like this are typically on a bell curve, so they start out slow, build up, then tail off.

Since laptops and desktops have a different "customer use patterns", they are at different points on the bell curve. Laptops have got to the, "we can't bury this anymore" point, desktops haven't, but they will - guaranteed. The biggest question is whether or not they will be under warranty at that point, not whether or not they are defective. They are.

If you look at the HP page, the prophylactic fix they offer is to more or less run the fan all the time. Once again, for the non-engineers out there, fan running eats a lot of power, so this destroys the battery life of notebooks. Basically, people bought a machine with a battery life of X, and now it is Y to prevent meltdown from a bum part. It doesn't fix anything, it just makes the failures take longer, hopefully past the warranty period, at a huge battery life cost. Fire up your class actions people, you got shafted.

Back to the engineering, we intoned that this was a cover-up of engineering failures by Nvidia. We also said that they probably knew what was happening. Think we were kidding? Read this, twice, linked again here for those that can't move their mouse to the left, it is that important.

If we knew a year and change ago that these exact parts had heat problems, think Nvidia did? Think the voltage difference between A02 and A03 is coincidence? This is a classic example of not meeting engineering goals and overclocking through brute force (voltage bump in engineering terms) to compensate.

HP and the others were blindsided by this, it happened far too late in the design cycle to compensate, and it looks to have been covered up hastily, badly, and eventually fatally. Blaming suppliers, OEMs and users is completely unfounded and says that NV is unwilling to properly address this issue, only hide from it. NV knew, they made silicon changes to fix another problem that directly lead to this problem.

Nvidia is covering this up, hard. All the usual sources are keeping mum on the topic with only a few daring to speak out. Given the sheer magnitude of this, their marketshare for notebooks was huge in the period, this could very well suck up most of their remaining cash. Don't underestimate how bad this is going to be for NV, we highly doubt $200 million will even begin to cover it.

If/when your card goes bad, increasing fan speeds will not help a bit/ I don't even think that is possible without hardware tweaks. But right now your card is cool so no need to worry.

But now It not working. I can't play games. T-T I can start it for internet Word ant etc. But can't ues GPU for Games. because GPU over heat

My gpu goes to 88C and this is not regarded as overheating. Over 90C is hot, over 95C is overheating, but not 80C. Does it downclock at this temp or does it shut off?

No there just isn't a software way to do it. Hardware modification is another story.

i don't think speeding up the fan would do you good, you heat issue may even get worse cause cranking the fan up (if you manage to do it anyway) uses more power and may cause more heat to be drawn to the mobo

its more effective to try new drivers, try the latest ones, they're rather good at maintaining stable heat temps

I think so good for me. I live in Thailand. It so hot. If i make fan full speed all time. My laptop will cool. It so good for my laptop and me.

Hi Unlimited,

Firstly I suggest installing the latest driver (http://forums.laptopvideo2go.com/index.php?showtopic=20810).

Next, there's a program called SpeedFan (http://www.almico.com/speedfan435.exe) that you can use to control fan speeds. Hopefully you have a 3-wired fan or it won't detect it.

If your temperature is still too high, you can buy a cooling pad (you put it under laptop), exemplary Zalman ZM-NC1000

Good luck with your problem

i agree, most core2duo's will suffice for your gaming needs. but trust me, the cpu WILL bottleneck your gpu if it is too slow, thats why i suggest the 2.5-2.6ghz.

that isnt the best core2duo, but its not slow either. its good performance for the price.

and i like the 9600M GT.

9800's are awesome too.

if not these two, go for a 8800 GTX or GTS.

Speed Fan can't use in laptop. It can't control fan
