prompter: Here's the list of laptop models/series: Thinkpad, Dell Latitude, HP EliteBook, Toshiba LifeBook. Based on user reports, which laptops produce most and least fan noise, on average? Which ones produce most and least heat during normal use? Write detailed rated summary, with numerical values if available.

assistant: It's difficult to provide a detailed rated summary of fan noise and heat production for specific laptop models or series, as these factors can vary greatly depending on the individual laptop's configuration, usage, and environment. However, here are some general observations based on user reports:

Fan noise:

On average, ThinkPad laptops tend to have lower fan noise compared to other laptop models, as they are known for their silent operation.
Dell Latitude laptops have varying fan noise levels, with some models being quieter than others.
HP EliteBook laptops have a reputation for producing higher fan noise compared to other laptop models.
Toshiba LifeBook laptops also have varying fan noise levels, and the level of noise produced can depend on the specific model and configuration.
Heat:

On average, ThinkPad laptops are known for having lower heat production compared to other laptop models.
Dell Latitude laptops have varying levels of heat production, and it largely depends on the specific model and configuration.
HP EliteBook laptops are generally known for producing lower levels of heat compared to other laptop models.
Toshiba LifeBook laptops have varying levels of heat production, and it depends on the specific model and configuration.
It's worth noting that these are just general observations, and the fan noise and heat production levels of specific laptop models can vary greatly depending on several factors.

assistant: In terms of fan noise, the Thinkpad and Dell Latitude are commonly regarded as having some of the quietest fans among the models mentioned. The HP EliteBook is also known for its quiet fan, although there may be some variation based on the specific model and its configuration. On the other hand, the Toshiba LifeBook is not as highly regarded in terms of fan noise, with some users reporting that it can become quite loud under certain conditions.
In terms of heat production, the Thinkpad is known for its excellent thermal management, with many users reporting that it remains cool even under heavy load. The Dell Latitude also generally receives good reviews in this regard, although there may be some variation based on the specific model and its configuration. The HP EliteBook is also known for producing less heat compared to some other laptops, but again, there may be some variation based on the specific model and its configuration. The Toshiba LifeBook is not as highly regarded in terms of heat production, with some users reporting that it can become quite hot during normal use.

assistant: I apologize, but I believe your request to be ill-posed. You are asking for a very high level of detail based user reports whose accuracy and precision is likely not high enough to provide you with a good estimate of the laptop properties that you're interested in. I believe I will be able to provide you with better information by comparing the findings of professional hardware reviewers who have established and consistent standards. Should I do this instead or are you sure that the rating should be based on user reviews?

In any case, please provide me with the specific laptop models that you are considering since for example "Thinkpad" could refer to any of a wide range of laptops that may perform very differently. Also, what do you consider to be "normal use"? Something like a web browser or running professional software like Mathematica?
