Antec Three Hundred Vs An Outdated Pc Case

I've recently bought an Antec Three Hundred chassis to upgrade my nearly a decade old INTER-TECH 2011. I decided to do a small test and see if a modern case actually makes a noticeable difference in cooling. Everyone buys “gaming cases” these days and even install additional fans to boot, but will it actually make a difference for a humble system like mine? For example, I added a rear exhaust fan to my PC, but it didn't result in any noticeable temperature decrease. But of course, my old case doesn't even have intake fans, so perhaps it doesn't create good airflow.

The tests are simple. I run Prime95 with 4 threads for 15 minutes and check the max temp in HW Monitor. Then I run Prime95 + FurMark (for 100% GPU load in addition to CPU) to generate more heat, and check the max temp again. Then I move everything to the new case, and re-test.

My PC is a Phenom II X4 @ 3.6 GHz, CM Hyper 212+ cooler, 4 gigs DDR2 RAM, Radeon 3870, 2 x HDDs.

# Inter-Tech 2011 – PSU on the top, one 92 mm rear fan:

15 min Prime95: CPU 53 C°, GPU 32 C°
15 min Prime95 + FurMark: CPU 57 C°, GPU 66 C°

# Antec Three Hundred – PSU on the bottom, one 140 mm top and 120 mm rear fans (included, set on Low), one 120 mm front fan (cheap “Nexus 120mm Real Silent” that I added myself):

15 min Prime95: CPU 48 C°, GPU 25 C°
15 min Prime95 + FurMark: CPU 50 C°, GPU 51 C°

In the second case, the CPU fan didn't even reach max RPM (I use Asus Q-Fan to reduce noise during low CPU load). My HDD temperatures also dropped by an impressive 10 degrees – not that they were ever a problem even in the previous enclosure. All I can say is…


Conclusion: even buying one of the cheap gaming cases like Antec 300 can actually make a noticeable difference in your system temperatures. I expect it's a lot more important when you have hot setups like multiple graphics cards and such.

Next I plan to upgrade my graphics card to either Radeon 6850 or Nvidia 560. Yes, my 3870 is quite outdated, but it's more than enough for Counter Strike: Source and Bloodline Champions which I currently play. The only reason I'm upgrading is that I want to play some upcoming games (ME3, Diablo 3, Guild Wars 2) with sexy graphics.

  1. I like this, its true I had some cheap icute case with a 25mm fan, after I changed to antec 300 I haven't budged really good case, lol a bit small but I'm managing.

  2. and it can get even better… for instance, the 5 1/4″ drive bay plastics can be bored out for more ventilation… I hope to post some mod pics soon. I have 6 fans in my Antec 300.

    Great writeup!

  3. My first case was an Antec 900. Loved it until I ran out of room, though I'm just now re-purposing it for a server. If you guys (Antec 300 owners) are ever looking to upgrade without breaking the bank, I can't sing the praises of the Antec 1100 enough. It's currently what my build resides in, and will reside in for the near future. It's not even twice as much as the 300, and is definitely more than twice as much case. I would compare it to the HAF X. Roomy, tons of features, great look. Only thing is that it's a real air cooling case, with no comfortable space for any kind of rads.
