A decent water cooler such as either of the two mentioned previously would be more than up to the job. The first one looks remarkably similar identical to the Corsair H110 that I use for a CPU with TDP 225W which works just fine for that and would possibly be overkill for your CPU. You might find that a smaller model such as the Corsair H55 would suffice.

The Intel i5-2500 is designed to run hot with a safe operating temperature of 72 deg C, somewhat higher than average.

Hope this helps
