WHAT?! No.
You have four options:
1. Get Sony to repair it for $150(Not recommended because you will lose all your data)
2. Get someone at an electronics repair store to do it for $40-ish
3. Find someone on Craigslist/online to do it for you for $40-ish
4. Do it yourself for $20(supplies)
Do not put it in the oven, use a hair dryer on it, or put it in the freezer.
If you are doing it yourself, you will need a few screws to open up the PS3, some thermal paste that you can get a Radio Shack, a heat gun(not a hair dryer), patience, and Youtube. Watch the tutorials. There are some with over a million views.
