Increased GPU temperatures on 7805u, out of the blue!

I have been playing the original Bioshock recently because I want to complete it before I start Bioshock 2. I was playing it for around 2 hours straight the other day when it became very sluggish and I was receiving very low FPS.

I alt-tabbed and brought up CPUID Hardware monitor and I was pushing 91 degrees Celcius on the GPU. These temps were with Dox's 195.62 drivers. These high temperatures have never been a problem before.

What are some things I should look for to reduce the temperature? My laptop is still under warranty from SquareTrade so I would rather not open it up and play around with the insides.

Can I undervolt my GPU to receive better temperatures? Is there a different BIOS I can flash it with to get better temperatures while keeping the same gaming performance?

Here is a screenshot of GPUZ after running 15 minutes of Furmark. These temps are with the 195.81 drivers:

 

Well if you have never cleaned out you laptop then you can get yourself a can of compressed air to remove the dust. Just turn your pc off and then flip the pc over and blow the vents out. If you want you can unscrew the lattes on the bottom to make sure you get all of it out. I do this like at least once a month.

 

I will have my fiance pick up a can of air on her way home. I have not blown out the vents since I bought it last year.

Any other suggestions if this does not resolve the issue?

 

you can try undervolting the gpu. this will get you lower temps and longer battery life. you can use this guide (typed up by llynx) on undervolting your p7805u

Has anyone but the OP had success in following those steps? It looks like a majority, if not all of the replies to that thread are of failures.

I would like to give it a try, but I am not going to bother if no one else was successful at undervolting their GPU.

 

I suggest cleaning out your fans first.
When I did my temps dropped from about 95+ to 68 celcius while gaming.

 

Wow - that is a big decrease.. I will definitely give it a shot. Thanks.

EDIT: While I am thinking about it, are there any specific areas that tend to build up a lot of dust and hair that I should really REALLY clean?

 

Its always where the fans are. Try cleaning the keyboard if you can.

 

Cleaning the keyboard? Do you mean just blowing it out with the can of air or taking the keys off?

 

I prefer disconnecting the keyboard and blowing it clean.

 

Disconnect the keyboard? How does that work? Lol

 

LOL Something like this. Check the Sticky thread for the disassembly. If you plan to get your fans cleaned by opening it up then you wont mind cleaning the keys thoroughly. Thats another place where you could have all kinds of junk (dust/hair).

 

Thanks for the info and sorry for being a pain.. haha

 

I used this guide to undervolt my GPU:

(scroll down to the GPU undervolt part).

Make sure you use the "-6" option when flashing to ignore the warning.

 

Yeah a lot of people on this forum have undervolted their GPU. That is the best article I have found and it's what I used without problems.

That is where I first learned about it, but I used the post 7earitup showed you.

 

Maverick always uses good settings. Maverick are you using the 196.34 desktop driver? What are your volts?

 

LOL. I took the settings off my sig. Those were the ones i used about a year ago to run 3dmark. And that was with the 179 driver i think. I dont overclock and dont game a lot. My present driver is 186.52. I tried the desktop one and rolled back. Since its of no use to me i thought i'll wait for the official release.

 

Ahh I see. Well moral look around there are good settings out there you can duplicate.

 

if im not mistaken most of the people that reported failures were people that have a 7811 fx. either way i used that guide and it worked for me.

 

Well - this is just wonderful.

I took off the panels on the back and blew them out with compressed air. Since the GPU fan was not easily accessible, I just blew it out through the existing vents and cover - a good amount of dust came out of the heat sink on the side.

I put it all back together and turned it on. I watched the fans and noticed that the GPU fan is not spinning on boot. So, I boot into Windows and load up Furmark. The temperature starts climbing at blazing speed - the fan is still not spinning.

So my question is, what the hell happened? I cleaned the CPU fan the same way and it is running fine.

Is it time to file a claim with SquareTrade? I do not want to void the warranty I already paid for - it does not expire until August of this year.

Thanks for all the help!

 

Most pbly the fan is blocked.

 

I blew the darned thing out though.. Why now is it all of a sudden so clogged that it will not turn at all? You can hear it trying to turn, but it never gets going.

I do not want to take this thing apart and then not be able to use the warranty I bought for it.

Are there any other suggestions or should I just backup my stuff, wipe it clean, and send it in for repair/refund?

 

I know that is probably not the best thing but try blowing through the gpu vent towards the inside of the pc and maybe what ever is blocking it will blow out. Blowing stuff in is better then nothing at all.

 

Try to use something to move the fan when laptop is powered off, then poweed up laptop again. Could it be a lossen cable done by air blowing?

If you have a spare laptop in handy, just call or email gateway support. They are going to try to help (which probably won't help), a service number will be given to you. Packed up laptop as instructed then be 2 weeks without notebook. I've done this twice already lol

 

I bought the laptop refurbished, so the Gateway warranty is already over. However, I did purchase an additional year of warranty through SquareTrade. I am just going to file a claim with them.

 

By the way, thanks for everyone's help. Either the GPU fan was really clogged or it was just it's time to go.

When I send it back to SquareTrade, they will either try to repair it, or they will refund me the money I spent on it, so I may have to start looking at the laptop market again.

I was thinking one of these:
