Try putting fresh thermal paste on them also try dusting your system.

The two BFG GTS250 OC cards have one empty slot space in between them. This is good enough for ventilation.

In addition to cleaning of dust and reapplying thermal paste, check these:-

 

1) The Antec 300's two front intake fans (blue rectangles in pic) are optional and do not come with the case. Have you installed both?

 

2) Have you setup a custom fan speed profile (eg with Afterburner) to increase the fan speed? Perhaps a 1C:1% is a good starting point.

 

3) What is the ambient/room temp? This is an important data.

 

4) What is the temp of the 2 cards when they are under load?

 

The load temp should be between 75-80C for the lower card.  The upper card will be in the mid 80C's.

Unless your ambient temp is much lower than average, idle temp of 55C (lower card) is not unusually high.

For example, the following review show a similar range of temp (ie idle around the mid 50Cs and load temp around 77C)

If you want your GPUs to run cooler that is fine but just to clear up a possible misconception, you can not do anything other than lower voltage, clocks, and load to decrease the amount of heat your GPU puts out. Decreasing the temperature your GPU runs at through methods such as changing the TIM, increasing fan speeds, or adding more fans will only move the same amount of heat more quickly away from your GPU core and into your room.

ambient temp is about 30 degrees celcius

only have a single intake fan on the front of the case, along with the top and back exhaust.

Idle temps-65 and 50
Load temps-81 and 73

im probobly going to modify my desk later on to help my PC breath a bit, right now it sits in a sort of compartment on the bottom left, and theres really nowhere for the exhaust air to vent from there, im betting if i cut some holes in the sidewall/back i can probobly get alot of the hot air away from the case and get all my temps to drop. reseating the heatsinks in the meanwhile is probobly a good idea
