After searching quickly what happens when a transaction is not confirmed for a long time:
If I understood correctly, either the previous transaction will end up being confirmed and your's too, or the nodes from the network will end up dropping it but look like it can take few days.

What was the transaction made the 2014-03-04 07:57:53 on your address? (if it's not too indiscreet to ask that)

Hi,
Your transaction have an unconfirmed input from another transaction (you can see the red U)

Which seems to not have enough fees.

Hello, although the delay this looks nice, can we hope to see Left 4 Dead 2? Which recently came on linux and is on 75% sale

73C° seems safe for me, my HD5770 at full charge is at 80-85C° and my HD4850 can go up to 110-115C° (it's mono slot) but only 90-95°C when mining.

The problem is your fan because above 85% of it's full speed, it's durability might significantly shorten.

So it should be better to reduce the fan speed to 85% and see the new temperature.
