In the SIVA PURANA Vidyesvara Samhita Translated by Shastri 1973 -
Suta said - Rudraksa is a favorite bead of Siva. It is highly sanctifying. It removes all sins by sight, contact and japas.
SIVA said - If a man is not liberated after Meditation and acquisition of Knowledge, he shall wear Rudraksha. He shall be freed from all sins and attain the highest goal. A Rudraksha of 3 Faces always bestows means of enjoyment. As a result of its power all lores become firmly established.

Klim...Obessiance...3 Faced Rudraksha Bead
In the PADMA PURANA Chapter 57 Translated by Bhatta 1989 -
THE LORD Said - The one with three mouths is Fire Himself; the sin earned in the past births of him on whom it remains is burnt as fire burns fuel. A wise man obtains that fruit which is obtained by worshiping Fire or by rites of honoring Fire or by offering the oblation of ghee; and also obtains heaven. He who wears a Rudraksa of three mouths on his body is like Brahma on the earth. It would burn all the sins due to wicked deeds collected in birth after birth. There would be no disease in his belly; he would not be sick. He is never defeated, and his house is not burnt by fire. These and all other fruits are obtained and destructive weapons are warded off. Nothing inauspicious happens due to wearing of Rudraksa of three mouths i.e. when a Rudraksa of three faces is worn on one's person.
In the RUDRAKSAJABALOPANISAD -
KALAGNI RUDRA replied - The one with three faces is Fire Himself, which on wearing pleases all the three Fire deities.
