You guys SHOULD READ what somebody posts before you are so eager to "help"...
Not too sure if "returning" and replacing like-for-like will solve the problem... Especially in the long run....
Based on the "many patterns" on this forum (and others), I see the situaiton as:
- Lion has problems. It isn't 100% and at times, makes the system work harder than it needs. This means more internl heat (along with hangs, freezes and weird video problems). Hopefully, Apple will provide immedate pathes to its many problems. For now, Lion makes a system "run hot". Heat = bad. For now, suggest staying with much temp cooler & more stable SL.
- IMO, these All-In-On boxes do NOT have enough lower box and upper box vent holes. The system is starving for air flow. Thus, why the top of the iMac box runs hot. A few years ago, I remember reading a post about the C2D boxes and their "cool temps". One poster perks up and says, "when i5,i7 chips and better video cards are jammed into the tight size box, their internals will run even hotter. Scary hot". Today, we see "many, many" posts about iMacs running hot. Scary hot. Hot to touch, HDs over 55C and many other "over the top" hot temps. All because their boxes lack "more" air flow openings. Will trading "box for box" eliminate this lack of air flow problem? No lickely. To me, if hotter items are inside a small box, you'd think they would install more (or larger size) air holes in top and bottom to compensate this increase as well... Guess they missed this common engineering sence as well.
- To keep `energy savings star` rating, the internal FAN RPMs are "too low". Increase fan RPMs (using 3rd parts softare) and one can easliy watch the iMac's internal heat go down. Faster fans = more air flow = cooler internal temps = great thing. Why must the fans run fast??? Because the iMac design lacks enough air flow openings at the top and bottom of their box. Remove the Memmory Simm cover (at bottom of the box). Does that cover removal lower the internal temps a few minor degrees? It does on my iMac box. Thus, proving more air flow openings = cooler insides.
After my iMac base warranty is completed (in 1.5 more months), I plan to remove its front glass, remove its insides and open its rear vent holes to "twice its size". And, I plan to add larger holes in the bottom of iMac box as well. Thus, allowing more (much more) vertical air flow within my tightly compressed iMac box. After this modification (to eliminate air flow "starvation"), I can then turn the fan RPMs down. Down to say 1,000 RPMs (instead of their current mimim 1,400 RPMs).
IMO, returning the iMac isn't the long term answer for its "too hot" insides situation. The answer isn't found within the box. The long term answer is looking at how the iMac box is designed (too small of space with too much heat generator items) and how this iMac box "vents" must be modified - to allow it to breath properly. That's the long term answer - that's being shown many times within the many "too hot / too hot" threads. Trading / swapping like-for-like isn't the long term soluiton. Thinking "outside the current box" is the real answer (for better internal cooling and less system hangs / crashes)....

) let it cool down for long enough to get back to room temp...turn it on and download the istat pro widget if you don't have it already...
