Sollertis wrote How does a Phat RGH Jasper differ from a Slim RGH Trinity? They seem very similar to me, but I've been told that Slims don't heat up as fast. Other than that I don't see any difference, but correct me if I am wrong.

They are the same. Phats in my opinion are easier to deal with. Slim sometimes have more issues.

Slims are better than phats. Hands down.

Slims are 10x better I have a Trinity Slim I had a Jasper though it RRODed on me though, Slims don't RROD!! Enough Said

I've had a Jasper RGH that has been great. No problems what so ever.

Thanks to Rodent_Modz

100% agreed.

Jaspers are the best of the phats, but statistically speaking slims are better.

Slims are more reliable.

Well, it depends on what you set your fan speeds to. My Corona heats up to 70 degrees celcius on auto and my jasper only gets up to around 60.

Not really. Regardless of fan speed, Slims are more newer technology and overheat less frequently. I've also never got RROD on a slim before.

From Wikipedia:

On August 28, 2009, SquareTrade published a report saying that "early indications point to the RROD problem abating in 2009", projecting that 1-year failure rates with the release of the Jasper chipsets might be below 4%, with actual fail rates for RROD problems at slightly above 1% in Q109, and total failure rates for all hardware problems at about 12%.[31]

In June 2010 Microsoft released a new "slimmer" Xbox 360. These models indicate hardware failure differently from the original; The outer ring segments cannot turn red anymore. Microsoft has said that henceforth errors will be displayed by the center of the power button changing from green to red.[32] Additionally Microsoft will no longer give a 3 year warranty for "general failure" errors, because the Xbox 360 slim "constitutes a whole new design". Microsoft now only offers the obligatory one year warranty.[33]
