Are they actually better for cooling than standard ones?! need to replace mine in the fez and was gonna get a standard replacement, but lookin on ebay someone is selling some that are ally with plastic side tanks. Price is pretty similar to what i was gonna pay for a normal one so IF?! they are better will prob go for one of these but wanted to check first what ppl think!!
