## Questions & Answers

**Q: are these silent or the standard howling?**
A: They aren’t silent but they are at least 90% quieter than the standard screamers. A point to note is that on the servers I've used these the cpu temps can be around 10-12c hotter than using the screamers so watch out for that. They move significantly less air.
