Lian Li PC-B71

Testing

Testing

Idle temperatures were taken after thirty minutes of sitting idle, and load temperatures after thirty minutes of torture tests using Prime95 to max out the 4 cores. Ambient temperature during testing was 22°c controlled by an air conditioner. The B71 was tested against a Cooler Master HAF 922 and Corsair 800D for comparison.  The hard drive temperatures were tested by cutting and pasting a 100GB random text file between the 2 hard drives 4 times and recording a maximum temperature over the course of the test. All fans in the both systems were run at 12v. 

• HW-Monitor - record and monitor all temperatures
• Prime95 - CPU & Ram testing
• 100GB Random text document copied & pasted 4 times between the 2 drives
• ATI Tool - GPU testing

Even with the hot swap bay at the front of the case right in front of the fans looking at the temperatures its easy to see that this case has no problems cooling our test system. In some of the tests the B71 actually manages to beat our bench mark case the 922 which is built to be a high airflow chassis. I think the extra space within the case is what helps keep the parts that bit lower, where they are fully able to breathe, therefore you don't necessarily need to force feed the components with fresh air like the 922 does.

 

Load results can sometimes be a case's downfall. They perform well on the idle tests but as soon as the component fans spin up or require airflow to help keep them cool they start to fail miserably. I'm happy to say that the B71 did not suffer with anything like this. Yet again it either matched or even bettered the 922. I have put the 800D comparison temperatures in there just to show you how well the B71 actually does perform.

 

It just goes to prove you don't need a case covered in fans to keep hot components cool. You just need a company to design a case that works well, rather than what's cheap and just cover it entirely in fans hoping that new enthusiasts will buy it because more must equal better. Before I slip into naming and shaming such plastic clad cheap and nasty chassis that should be avoided like the plague lets get over the page quickly to the conclusion.

I don't normally go for LianLI's but that does look a nice case (apart from the gash blue fans). Great review as always m8.

As ever though fans are a simple fix, we are hardly likely to keep the back stock black fans anyways are we

Great review, seems a pleasant enough case stock, but lets see one with a 120.3 in the roof :P

Great Review Tom!

im abit conserned about the hot swap bays tho, as the green color of the back plate might get in the way when you're modding?

well love the review and the youtube videos! great id with the new "Lian Li B71 - What Mods Are Possible?" want to see more of those in the future.

Cheers //// Apans

Good review, great case!

On my next big rebuild (i.e. socket change, totally new system, happens every 4-5 years or so), I'll seriously consider this. Can't quite justify dropping 250 on a case right now when the P182SE does me fine.

I liked how you try to get across what good case cooling is. I never would have expected it to perform so well if I'm being honest. Perhaps I underestimated Lian Li, though I've been after one of their cases for a while, but ended up with two Antec cases instead, mainly due to price.
