After removing the motherboard, you will remove the heat sinks from the CPU and GPU. They are removed by prying the clamps off the back of the motherboard. After removing the heat sinks, you will need to scrape off the old thermal grease and apply a new layer. You may need to use acetone or nail polish remover to remove the old thermal paste. After removing the thermal paste, you will remove the squishy thermal pads. Replace the heat sinks and the thermal pads with the new parts and reassemble the Xbox. There are many establishments, both online and in brick-and-mortar shops, which offer Xbox repairs. They will essentially be performing the steps outlined above.

Darkening of underarm skin can have a number of causes, including dead skin accumulation or a reaction to a deodorant. If you find this darkening disagreeable, you may want to lighten the skin. There are commercial skin lightening creams, but these are not well-regulated and may contain harsh chemicals. Luckily, there are natural ways of lightening the skin. Some of the simplest and most effective include:  Try using honey as a simple and safe remedy that may help lighten skin. Apply raw honey over your armpits and leave it on for about 15 to 20 minutes. Then, rinse it away. You can also combine a ½ tablespoon of honey with a tablespoon of yogurt or ½ teaspoon of lemon juice to intensify the effects.  Often, dead skin cells cause underarm skin to darken, so regular exfoliation can also help. Exfoliants can dry out and irritate the skin, so choose a mild one. You may have an allergic reaction to a component of a deodorant if you notice persistent itching, redness, swelling, etc. on your underarms. Research has shown that a deodorant containing glycerol and sunflower seed oil can reduce irritation after shaving.  If your deodorant does not seem to reduce underarm perspiration or odor, or if you have a reaction to it, talk to a medical professional about stronger or alternative products. Sweating, hair growth, odor, and darkening of the skin are all minor issues that normally arise related to underarms. These can be safely taken care of using the steps above. However, if things are out of the ordinary, it could be a sign of something more serious that needs professional attention.  If sweat smells fruity, it could be a sign of diabetes, while liver or kidney disease can cause sweat to smell like bleach. Consult a doctor if you notice an unusual smell or a marked change in smell. Darkening of the skin of the underarms can happen to anyone, but is found more often in people with insulin problems, pituitary problems, certain infections, and a range of other issues. Contact a physician if you are concerned or if the darkening arises with symptoms of another problem.
