P-7805u Annoyingly loud GPU fan!

Hey all. Have a question. My computer is loud. The GPU fan seems to be on full blast all the time from startup. Even under load playing Crysis, CoD, whathave you it never gets louder and it operates under normal temps, never overheats (because the fan is always going).

My question is: Is this normal? Can any other 7805u owners attest to the fan being a beast, I understand it has a pretty hefty GPU in it and it needs to push a lot of air. I would be fine if it did this when it started heating up when playing games but when its idling? Give me a break!

Tried Rivatuner and Speedfan and had an IT friend try and tweak voltages and the fan will not budge. Please someone put my fears to rest, am I to be stuck with this mini-jet fan for the rest of my computer life?

Thanks!

 

My fan never ran full blast all the time. have you tried cleaning it out?

 

Get it cleaned out, and better thermal paste.

 

I have blown out the fan with air but I haven't disassembled it and got in there. I shall clean it and apply thermal paste. Can someone show me a pic of where to apply the paste? Or is it just one spot on the gpu?

My gpu idles at 48-50C..is that normal?

 

which bios version?

 

9C.10.00 is my bios version.

 

your fan should cool the gpu enough to shut off. Something is amiss...............

 

Update to 9C.17, that is the one I am currently using and the best one for fan control Imo.

 

I am going to purchase some thermal paste today (ICD7) and get in there and reseat it. I've never had problems with overheating but something must be amiss if the fan is constantly going full blast. Do you think upgrading the bios will help? Will there be fan control options?

Also, any helpful tips on where to apply the thermal paste on the gpu? I hear there are chips that don't have thermal paste on the sinks, should they have some? Any pics or videos would be greatly appreciated!

 

I would say its the driver version you're using. Have you switched drivers recently? Maybe you should try another driver and see if that helps. What are your idle clock speeds? You should check to see if the GPU is downclocking, I had trouble with my old 260m on certain driver versions the GPU wouldn't downclock and therefore my GPU fan would kick on and cool down GPU then off then back on, a nice bootstrapping cycle.

 

I can check when I get home but I am faily positive that my first move was to download the most up to date gpu drivers off nvidia.com. there are no fan control options anywhere and the fan is still a blazin'.

 

Every driver version I've had on mine has never caused 100% fan. In fact as it turns on and the bios ready's to post the fan shuts down. Before 9c.23.00 with powermizer off the fan would only every couple of minutes or so click on medium for a few seconds. The system should not do what his does.........

 

Okay heres the specs on my GPU: 600/799/1500 and the video BIOS version is: 62.94.48.00.09.

I bought this laptop used and i haven't tweaked with the values at all so im guessing this is stock. Im just crossing my fingers its a problem with the GPU needing to be reseated on the heatsink...but then again I've never had problems with overheating so that may not be the issue at all. It's so aggrivating I have no idea how to make this fan shut up!

 

I tore my computer down to the motherboard using the disassembly guide. When I applied my thermal compound (AS5) to the GPU I also applied it to the 4 chips that sit around the GPU ensuring they made contact with the heatsink. I also reapplied the compound to the CPU and a dab on the northbridge (previous owner had already made a huge mess with his own reapplication of compound. Put it back together using the guide from the last step to the first.

Turn her on and the LCD screen is completely black, like it's not getting power. Hooked it up to my LCD tv with VGA cable (used before, it works) still no signal. Did I mess up the GPU by placing compound on those 4 chips? Should I take it off? Any thoughts on what it could be?

P.S. fan came on roarin loud as ever. It has to be a problem with utilities/driver/signals from the GPU telling it it needs to be 100%. Something is telling the fan to go, how do I change it? Ack!

 

no those memory chips can have compound on them that is not an issue. at first boot to dst table it does go 100%, once that is over then it should slow down going to bios than as fast as need be after that.

Do you have it all together running again? if so next step may be to try another bios. Mine originally was 9c.11.00 and upgraded to 9c.12.00 then 9c.17.00 under vista then too 9c.23.00 now under windows 7. Maybe it is time to try another bios version. I know 9c.23.00 will normally cut the fans on at apr 80c down to temp of about 68c then let it rise again to 80c..............

 

Is AS5 thick enough to bridge the gap between the:

GPU memory chips and heatsink

Northbridge chip and heatsink

 

I used The Thermal Past Tanware recommended (can not remember the name) on the GPU, North Bridge and CPU, no issues. I was worried I did not have a thermal pad for the North Bridge, but I have had no heat issues for two months now.

 

AS5 is not a god gap filler. Since there is none on the GPU memory chips at all originally it shouldn't hurt. I haven't seen that though so if thee is a gap ICD is a much better choice.

Do not use AS5 on the NB though, that is a recipe for trouble...........

 

I dont have it running yet. I am going to hook it up to a monitor and see if its the LCD screen or the GPU that is not working. The Northbridge already had a HUGE gob of some TIM that the previous owner had put on and its been working for a year since ive owned it. I just added some AS5 right over the top. I put big gobs of AS5 on the GPU memory chips and checked to make sure they are making contact with the HS. I dont know what I did but when I turned it on now the LCD screen is completely black, seems no power is getting to it either, yes the cable is connected under the media bar!

 

The gobs of AS5 should be removed from the memory chips as the AS5 may squeeze out onto the pins on the chips and cause trouble. The manufacturer states that AS5 is "very slightly capacitive and could potentially cause problems if it bridges two close-proximity electrical paths."

I agree with TANWare that ICD is a much better choice for this application.

 

A few pics, I am thinking it is the Northbridge having AS5 on it. It's the only chip that has electrical components that could have their connecticivty askew from the silver compound. The GPU memory chips dont have any AS5 oozing over the edges, its right on the top only. Any thoughts on why there is no PC activity? I hooked it up to a monitor and got nothing. the fans go but theres no beeps or anything.

 

The problem with AS5 on the NB is it is so thin it will not fill the gap properly. You need either the pad, ICD or a 1mm copper plate to act as a shim. if there is a gap inbetween the memory chips and the GPU HS you again have to fill the gap with something other than a thin TIM.

Since there was nothing over the memory chips your option is to leave them alone. Be 10x more diligent putting it nback together than pulling it appart. It is very easy to mistake thinking a cable is connected when it is not proper seated or locked, this even includes locking down the CPU from the twist lock. just one mistake on these is a non boot.

Another thing to try, if you are sure all is well, disconnect the cmos batter with AC unplugged and the regular battery out and hold the power button for 30 seconds. This should clear cmos. That can easily have been a issue as you have handled the board and static is all around etc.............

 

OK I tore it down again and stripped the MOUNTAIN of thermal paste off the NB and the GPU memory chips with 91% iso and coffee filter. Reapplied AS5 to the NB and put it back together, its booting!

I am going to look around for a 1mm copper plate to shim, I cant wait 5 days for ICD7 to ship.

I am going to upddate the BIOS...what's the best version for fan control? The fan still goes full blast. Will BIOS update help?

 

I updated the BIOS to 9C.17.00 and it made no changes. The fan is still going full blast. Will nothing work? Is my computer retarded? Should I try 9C.23.00?

 

9c.23.00 will let it get hotter before kicking the fan on normally. My concern is you say it NEVER kicks down. As far as I know everyones does especially at DST table posting............

 

Yep, I updated to 9c.23.00. 0 changes. It kicks on at startup and never lets up. cleaned fans and heatsink fins with a toothbrush, 100% dust free. I am close to taking it to a shop. I doubt they can do anything. I should just give in and face the fact that its just going to be super loud for its life.

Any place I can buy a replacement fan?

 

did you make sure the GPU fan was plugged in properly when you had it appart? The board should control the GPU fan speed but eiher somthing is amiss with the board controler, the fan is plugged in wrong, the fan was wires wrong or maybe they replaced the fan with the wrong one........

 

I read somewhere that when some gaming laptops are sent in due to overheating GPUs the company just tweaks it so the fan runs 100% as a fail safe of it happening again. Think that's plausable? I will take out the GPU fan and take a pic. Hell ill even record a video of the noise haha.

 

What are you temps?? Are you even looking at this? As others have stated before, usually a TIM will NOT fill the gap between the heatsink and the chipset. This is especially true of a TIM like AS5, that stuff is really thin, messy, and if it gets on anything it's not suppose to its highly conductive and could cause you problems.

The fan is most likely not kicking down because the temps are really high, and your laptop is doing all it can to prevent itself from running at ridiculous temps. get HWMonitor and check your temps.

Order some 1mm thermal pads on ebay, they are cheap and will save you a headache. Even though these weren't between the memory and the heatsink, if there is room there, I would definitely put them there to improve heat transfer. Also put a pad between the chipset and the heatsink. I used this on my old G51.
EK Thermal Pad Sheet - 160mm x 155mm x 1mm - FrozenCPU.com

I recommend a thicker TIM if you have a large gap between the GPU and the heatsink. Since my old G51 had a large gap I had to use a very thick TIM to make a good connection. Shin-Etsu is great and gave me good temps. Newegg.com - MASSCOOL G751 Shin-Etsu Thermal Interface Material I would get two or three of those, the tubes are like one/two use applications, and if you mess up or want to experiment you won't want to wait for more to ship. Also this stuff is non-conductive, so if you get it on anything it shouldn't cause problems.

 

Didn't really want to necropost, but I googled to this thread and since this problem was never really solved, I'll write what I did to solve my problem so I may help others with the same problem.

I had the exact same problem, but it turns out that the reason why was I had my power settings on performance. As soon as I turned it down to Balanced, the fan stopped going on full blast all the time. However, it still made a lot of noise as it sputters here every second even though the gpu is super cool. Moreover, the longer you leave the laptop on, the louder it gets, even with good ventilation.

 

This is extremely good.

CPU: T9900 <-- You can get one of these for about 100 dollars now from China.
Adapter Type: GeForce 9800M GTS, NVIDIA compatible
Driver Version: 9.18.13.1422
BIOS Version: 9C.23.00_A_A (currently published and supported by Gateway)
External Second Monitor: Gateway FHD2400

My temperatures posted by Throttlestop range from about a 66C to 82C. My fan throttles up each time the temperature climbs the ladder to 80C to 82C. I drops back to 66C or so and starts climbing again. With only one monitor active, the integrated LCD or external monitor, the temperature stay lower or climb slower. I am considering a retro upgrade to BIOS version "9C.17.00". My understanding is that the fan is managed differently with the fan operating periodically or in fluctuation mode rather than on demand at 80C. So, the average temperature stay lower which is good for gamers. The only downside might be a greater consumption or use of power meaning a battery would likely not last as long.

Some have also argued that going backwards with video drivers may sometimes be a plus. Sometimes new drivers take advantage of or realize new hardware features. But, other times new software drivers may have features that the hardware cannot use and might cause a bug to occur. Just a guess here, but going backwards is sometimes good. I am using a video drivers that in too new to be supported by Gateway, but is supported by NVidia. I have found myself stepping back one driver version or so because I had a problem. The current driver version appears to pass. But, the NVidia Control Panel does not have add-on for Fan 9800M GTS is not have Performance Group support for Fan Control ( see NVIDIA DRIVERS 6.08 ).

Double post, this is reviving a very old thread though.
