Hello. This is my first post so if you need any additional information I will do my best to fill you in.

Before I come with my question, it is probably best that I tell you about my problem and how I ended up in my current situation. Disclaimer: This will probably be a long post, but please bear with me:

I used to be able to game just fine on my graphics card (Nvidia Geforce 9600 GT, 512 MB). One day while gaming, I could feel that it was under stress because I was getting significantly lower frame rates than I used to. Ignoring the warnings, I pushed my GPU further which resulting in me getting a black screen. This was followed by an odd smell which smelled like a mix of hot air and perhaps something metallic (not sure, but it seems the most logical description). I quickly force shutdown the PC and left it off for a while.

When I booted up my PC again, everything seemed fine until I noticed that my GPU was idling at +100 °C (+212 °F). I jumped into a game and the frame rates seemed normal and stable. But when I got into a situation where there were a lot of particle effects, the frame rate plummeted.

I immediately quit the game and saw the GPU temperature was around 135 °C (+275 °F). With this, I shut down the PC and went to sleep. The next day, I opened up the case, dusted off the insides, detached the GPU, dusted off its fan and reattached it to the PC. When I boot up my PC now, the temperature of my GPU starts at around 30 °C (86 °F) and steadily climbs up to 80-100 °C (176 °F – 212 °F) where it remains stable climbing up and down. This temperature when idle is when CPUID Hardware Monitor and MSI Afterburner states that the fan speed is at 95%.

Something is probably wrong and my first thought is that, other than something may been partially burnt, the fan of the GPU might not be spinning. I’m not sure because when I set the fan speed to a minimum (25%) in MSI Afterburner and GPU temperature slowly climbed from 80 °C (176 °F) to 90 °C (194 °C) at a pace approximately around 1 °C (1,8 °F) every minute. After I turned the fan speed up to 95%, the temperature steadily lowered to 80 °C again. Because of this, the fan might be spinning or it might not. I have seen to fan spin with my own eyes while the PC is on.
Is it possible for the fan not to spin even if CPUID Hardware Monitor and MSI Afterburner show the fan speed up to 95%?

Any other hardware in my PC seems to do just fine. The motherboard, CPU (all four cores), and my two hard drives idles at around 40-50 °C (104-122 °F). This makes me think that it is a problem only affecting my current GPU.


This situation has led me to believe that I probably have to replace my GPU if I want to continue gaming. The GPU I have in mind is the Gigabyte Geforce GTX 650 Ti 1GB OC (GV-N65TOC-1GI). Gigabyte Geforce GTX 650 Ti 1GB OC has a PCI-E 3.0 x16 interface while my Nvidia Geforce 9600 GT has a PCI-E 2.0 x16 interface. Is it possible to use a PCI-E 3.0 x16 GPU in a PCI-E 2.0 x16 slot? I have heard it should be possible without any performance issues.

The Gigabyte Geforce GTX 650 Ti seems to fit quite nicely, but I have seen that its PCB is ATX. The problem is that the size of my case is a micro-ATX (even though it states that my PSU is sized for an ATX) - I estimate my case to be a mid-tower. Will the Gigabyte GPU fit into my case even though it might be a micro-ATX case and the GPU an ATX fit? And do you think that the Gigabyte GPU is a variable upgrade from my Geforce 9600 GT – gaming wise and does my PC meet the minimum requirements of the Gigabyte GPU?

The GPU will be used to primarily run World of Warcraft, Battlefield 3, Dota 2, League of Legends, and other current games at resolution of 1680x1050. I am willing to tone down the graphics quality in return for performance (as long as it is noticeable).


My PC specifications are:

Computer model: Fujitsu Siemens Scaleo Pi 2680
Motherboard: Fujitsu Siemens MS-7379VP
CPU: Intel Core 2 Quad Q9300 (2,5 GHz, FSB speed: 1333 MHz, 6MB L2 cache)
RAM: 4 GB DDR2 (I believe) and probably a DRAM Frequency of 667 MHz (according to CPU-Z)
Hard drive:: 1 TB SATA2, 7200 rpm
PSU: 400 W – I do not know anymore about it, but it states the voltage is 220-240 V with a frequency of 50-60 Hz
OS:: Windows Vista 32-bit

Additional information about the specifications of my Fujitsu Siemens Scaleo Pi 2860 PC (it will attempt to download a doc-document): http://uk.ts.fujitsu.com/rl/service...onsumer/Scaleo/Scaleo_P/ds-SCALEO-Pi-2680.doc

This marks the end of my post. I apologize for its length, but I felt that I had to give you everything I knew in order to receive the best possible advice. Thank you very much for reading my post.

I have a 9600 GT that would hit 130C+ and crash the PC. I took the fan shroud off and the heatsink was blocked with dust. I removed the heatsink, cleaned it off, added new thermal paste, and reinstalled everything. Temps were back to 70C at load and no more crashes. I recommend you do the same.

As for the fan, it is possible the fan is dying, so replacing the heatsink/fan with an aftermarket heatsink/fan should fix that. My GTS 250 fan died and I replaced the fan to keep it running. Of course you have to consider cost when replacing parts on old tech, as replacing with a new card may be a better overall cost option.

Is it possible to use a PCI-E 3.0 x16 GPU in a PCI-E 2.0 x16 slot? I have heard it should be possible without any performance issues.

Yes, the 650 TI should work just fine. PCI-E 3.0 is backwards compatible, and no card today will be limited by PCI-E 2.0.

Will the Gigabyte GPU fit into my case even though it might be a micro-ATX case and the GPU an ATX fit?

You'll have to measure the length of the card vs the 9600GT. If they are similar, check to see how much room you have at the end of the card. If it's already a tight fit near the hard drive cage, then you'll have to factor that in.

And do you think that the Gigabyte GPU is a variable upgrade from my Geforce 9600 GT – gaming wise and does my PC meet the minimum requirements of the Gigabyte GPU?

The CPU should be fine, and you will see a significant performance increase and should be able to turn up the graphics quality quite a bit.

Regarding the sizes of the two GPUs, I can see that the Gigabyte GPU measures:

Height=4.2 cm, Length=18.7 cm, Width=13.7 cm according to Gigabyte's homepage.

And the Nvidia Geforce 9600 GT is stated to be: Height=11.12 cm, Length=22.86 cm/19.81 cm (for the slimer version), Width=Single Slot

I don't know how wide the term "single-slot" is. Is it a manufacturer form that everyone builds after like ATX and micro-ATX forms? And is the Gigabyte GPU a single-slot GPU? You only mentioned the length. Does the height and width play a factor?

If I judge per eyesight and according to the dimensions, then the Gigabyte should be smaller in all regards:

Here are two images of the GPUs

The 650 TI is a dual slot card. This means the heatsink/fan is so large it invades the expansion slot below the GPU, thus rendering that slot useless for additional add-in cards. If you don't have anything in the slot below the current GPU, then you should be fine. The length is also shorter than the 9600 GT, so you are good there as well.

Well, if I only have one PCI-E 2.0 x16 slot, then it should not be much of a problem. I'll make sure to check how the space is around the GPU next time I open up the PC.

No motherboard will have two PCI-E x16 slots next to each other. You will either have a PCI-E x1, or a PCI slot, and if it is occupied then you can probably move that card to another slot (if another slot is available).

Well, I have:

1 PCI-E x16 slot
1 PCI-E x1
2 PCI

And I believe that my GPU is the only hardware that occupies any of those slots. If that is the case, then wouldn't a dual-slot GPU fit in fine?

Can you name any other hardware that could occupy any of the slots mentioned above? I don't have any sound card - I use the sound integrated with the motherboard.

Yes, the dual-slot GPU will be no problem.

The other types of cards could be anything from SATA/RAID card, wireless/LAN adapter, USB/Firewire card, TV tuner, additional graphics card, etc, etc.

None of those sound familiar. I only have a motherboard, CPU, PSU, 2 hard drives, 2 RAM sticks, and a GPU..

Sounds like I am almost ready to go. The only thing on my mind is if a dual-slot GPU like the Gigabyte Geforce GTX 650 Ti 1GB and its own fan will be able to run under acceptable temperatures in a mid-tower case with limited air flow and no case fan?

The only fan I can see in the computer is the stock fan and heatsink located directly over the CPU.

If the 9600 GT ran fine for a couple of years or so then I don't see why the 650 TI wouldn't, but if you can, add a rear case fan anyway.

Yes, that's pretty much how you do it. Use an anti-static bag like he did if possible, just don't work on the floor. You'll need #2, #1, and maybe #0 Phillips screwdriver, Isopropyl alcohol, cotton swabs, and thermal paste. Canned air would be nice, but it's not necessary.

When adding the thermal paste, don't spread it with your fingers, just put a thin X in the center, about halfway across the chip, and put the heatsink back on. The pressure of the heatsink will spread it out just fine, and with less bubbles than his method.

Good luck! :)

One last thing:

If I get a new GPU like the Gigabyte one, will it then damage the GPU or the fan if I manually jack the fan speed up to maximum speed everytime I open up a game to ensure as much cooling as possible? Or could it potentially cause damage to it?

That would be overkill, and might make the noise a bit unbearable. The problem with your card overheating is not the fan speed, but the clogged heatsink after years of use. Making the fan run even higher than default will also shorten the life of the fan. Even with limited case cooling the new card should be fine.

Okay. I'll try to open up my 9600 GT and have a look at the heatsink. When I dusted it off, I only dusted off the exterior and tried to get as much dust out of the fan without opening it.

If that does not help then I'll look for a new GPU. Thank you very much for your time. You have been very helpful.
