Down-venting PSU - problem?

[ssmtoms]

I'm replacing my current PSU which has a fan blowing out the back of the case with a new PSU that has to be installed facing downward and the fan blows into the case. I'm wondering whether this will cause too high temp within the case.

There is another fan that vents to the outside but don't know if it's enough with the PSU venting inside the case as well.

Thanks for any help.

What PSU and case do you have?

That PSU fan pulls air up from inside the case and blows it out the back.
I'm not sure I know of any quality PSUs with that dual-fan arrangement though, and I do know of some Chokemax PSUs that do (the ones that croak violently, taking other parts with them). What is the brand and model?

Actually I found out that the fan is on the bottom of the unit, but it blows upwards into the power supply and exhausting out the perforations on the back of the power supply. So should be ok.

Thanks for your suggestions.

ssmtoms - I see you figured it out before I had a chance to post. Modern psu's have a fan that pulls in warm air from inside the case and exhausts the warm out the back of the case. It helps with cooling.

That's why I was wanting to know what PSU he had. I'm not familiar with any modern PSU's that flow the air in reverse.
