GPU Running Unusually Hot

Hi Guys. It's been a while since I've posted here. More significantly, life got busy and it's been a few years since I've actively kept up with recent developments in hardware.

These days, the only game I play is Skyrim. I recently had some incidents of my computer shutting down in the middle of a game. (I don't mean a CTD; the computer would completely shut down.) It got a little worse and I eventually figured out that the graphics card was overheating. My card is a MSI Twin Frozr II HD 6950 (I use the heat sink that came with it and I don't overclock it). I checked it out an noticed that the fans on the card were not spinning. After trying a few things, I found that if I manually turn the fans a little bit with my finger then they will start spinning normally. Now, whenever I turn my computer on I use some canned air to give them a jump start and they work. As long as the fans are spinning. my computer does not crash while I play Skyrim.

However, the GPU still seems to get pretty hot. I use TechPowerUp GPU-Z to monitor my card. There are four different "temperature" readings. Here are the temps that I notice for those four readings:
GPU Temp. #1: Around 55C at idle and between 65C and 70C during Skyrim.
GPU Temp. #2: Around 60C at idle and between 70C and 75C during Skyrim.
GPU Temp. #3: Around 65C at idle and between 75C and 80C during Skyrim.
GPU Temperature: This usually sticks pretty closely to GPU Temp #1.

Here are my questions:
1) Is this actually hot? I've never actively monitored my temperatures. It seems hot to me but I'm not sure.
2) If it is hot, then is there something I can do to help? My case is full of fans and I've been pretty careful to make sure that the fans are pointed properly to optimize airflow. If it were a CPU I would try removing the heat sink, cleaning the old thermal paste, and applying new paste but I've never tried that with a GPU before. Is that something I could/should try?
3) My card is old and it might just be on its last leg. If you think I need a new card, what are your recommendations? I don't want to spend a lot of money on a powerful card. I only really want something that can reach the performance levels of my current card. Skyrim is definitely the most intense thing that I do these days. I guess it would be nice to be able to run the next Elder Scrolls game (and not necessarily and really high settings or anything), but I don't have a lot of money to spend on a card. I don't want to give a definite price range, but I don't think I can afford more than $100.

Other Notes:
>>I built my computer in the summer of 2011 and I got the card for Christmas in 2011. Here are the specs:
i5-2500K (not currently overclocked) with a Xigmatek Loki HSF
ASUS P8Z68-V Pro
MSI Twin Frozr II HD 6950
G.Skill Ripjaw 16GB
Seagate HDD (my SSD failed a couple of years ago)
Corsair HX650
Zalman Z9 Mid-Tower
>>I do use a few mods with Skyrim but nothing which significantly enhances the graphics. I don't use an ENB or any mod which increases resolutions or overhauls the visuals. (Making games as beautiful as possible generally isn't my priority.)
>>I would prefer to buy from either Amazon or Newegg but I am open to other suggestions. I live in the United States.

Thanks for your help!

1. The idle temps do seem rather high, but the load temps are fine so I wouldn't worry.
2. You can definitely re-paste your GPU. Once you remove the cooler, you will see a plate that cools the VRM components. You can remove that too and replace with new thermal adhesive tape if you like. Applying new thermal paste is actually not a bad idea at all on an old card like yours.
3. If you feel like your card is on the outdated side and feel like upgrading, I'd have some fun with it first since you still won't find anything better for $100. The 6950 is actually just a 6970 with disabled shaders. You can unlock them and basically have a 6970 (how awesome!) by using a simple flash utility. Plenty of guides out there including this one...

Thanks for the response. A couple of follow-up questions:
4) What are safe operating temps for a GPU? At what temperature should I start to get worried?
5) Just out of curiosity...if I did want to go out today and buy a card that got similar performance then what would you recommend? Over on newegg I can't even buy a 6950 and they only sell one 6970.

80-90 C is okay. There are some protection features built in though. The card will slow itself down or shut your computer off if it gets too hot.
The HD 6000 series has been discontinued for a long time. It's been superseded by the HD 7000 series, R200, and now R300 cards. I estimate it would perform similar to a 750 Ti or R7 370. Both hover around $150 atm and consume less power.
