Lian Li PC-V1000 cases and air flow pattern

FYI, these are reverse ATX cases

On the basic PC-V1000
http://www.lian-li.com/Product/Chass...C_PC-V1000.htm

The case has two 120mm fans the fan in the front blows air in and the second fan at the rear and near the CPU sucks air out. Seems like a nice air flow arrangement.


PC-V1000 Plus
http://www.lian-li.com/Product/Chass...-V1000plus.htm

The reaming cases in this series have the rear fan near the CPU blowing into the case. These models have another 120mm fan near the top rear of the case sucking air out.

My question/thought is why blow that hot air (after is crosses the CPU) into the case. Is it not better to suck that hot air out is the case ASAP?

I’m wondering if I could not just turn that fan around and suck the air out. I’m using an Asus A8N32-sli MOB with an Artic Cooling Freezer 64 Pro on the CPU. With this heat sink and the rear fan reversed the Freezer would blow the hot air right at the rear case fan which would pick it up and blow it out of the case the rest of the way.


Any thoughts on this.

Thanks

You will like the plus I series (there is a Plus II now)

The little extra rotary fan at the back sucks air out.... usually hot air from the GPU....

In my opnion Lian Li still make the best cases for air cooling.

I have seen people convert 3 cd rom bays into an extra intake in the front of their PCV 1000s....

Thanks, After looking into it more I'm looking at the PC-V1200 Plus II. Still wondering about the air flow though.

The alternative is to blow cool air into the CPU cooler fan. After all, isn't that the most important thing to cool?

Airflow management is kind of trial and error. The basic concepts are:
More is better.
The CFM rating of the intake fan(s) should be approximately equal to the CFM rating of the exhaust fan(s).
There shouldn't be any dead spots (little or no air circulation) anywhere inside the case.
