The parcel came quickly. The seller packed well in a large navel. And now closer to the case ..... I have an old MSI ms-1761 gaming laptop, it's gt780. Of the rubber seals, the largest one fits less tightly. In general, the thing is working and with its work copes. The turbine blows more than my regular, the air at the outlet is warm, but I did not see a special effect of lowering the temperature. As an example in aida64 launched a stress test at the beginning without a turbine, and then restarted with a turbine. Perhaps it's in my laptop, but it's clean, thermal paste is better than mx-4, but why is it at a temperature of 60 + starts a trotting, it drops down down By the fact, this thing can help someone, but in my case there is no effect.
