i like to open my side panel...looking good so far..i open 4 last 6month..
nothing nesting in my pc...

i have to open my side panel in this moment so that i can using a blower fan to cool down my north bridge. still waiting the TR chipset cooler to
arrived.

my processor ever once rise to 56C.. but ever since i add in VIZO cooling fan in my casing then the highest temperature is only 46C... haha

Open or close case depends on the user.If your using WC in a air-conditioned room,use a casing.
If you use a air-cooling in a hot temperature room,open the case.

ya.. if dont have air con, open case does decrease the temp quite alots..

and u can add up table fan face the rig

it also help decrease the temp

Agree wif bro hengmy ..in a non-air conditioned room..opened case might lower the temp..

well...i think it helps reducing teh temp if teh casing dont havegood intake fan..and...erm...opening saide panel of casing like Cm COSMOS S...will only affect its airflow....

put it like this la.

casing best closed. but if casing airflow really suck, then you really no choice but have to open la.

Agree with this too. If ur worried bout casing, chances are that ur not one to go for cheapo vanilla cases, right? Decent cases are usually pretty well designed for ventilation (except for some). If ur having problems with heat, then maybe u can manage ur wires a bit (with cable ties or tape for cheap fixes), add some fans (need some ventilation planning) and a better thermal solution for ur proc (heatsnk, fan, wcool, etc). That shouldnt pose a problem

i totally disagree

Why? good ventilation means better heat dissipation out of the case. open case means better moderation of heat. but that doesn't mean heat will go out due to no exchange flow or wind to swap difference in atmospheric temperature. Unless you blow with a table fan.

if open always make sure no spider web la

Hmm.. based on your question stated for TS ..
I would prefer to use other sorts of cooling method instead of opening the CPU side cover to expose to the air ...
Avoiding it from being exposed to risk .. and there isn't much difference with the temp. unless you turn on the aircon or maybe a few fans blowing on it ...

On thermal performance, as usual, google for ur target case's reviews first before getting anything. If u already have a case and wanna make do with it, then ur choices other than an open case is thru modding, adding cooling components, and or rearranging ur stuff inside. Thats all i can think of anyway

I always believe opening the casing (opening the side panel) while it's operating is the best cooling method but this will produce 2 disadvantages:

1. Fan noise generated from your cpu and power supply.
2. Collecting dust.

So to overcome these 2 problem, u can always change the cpu or power supply fan to a after market low rpm fan, and then while the PC is not operating u can temporary close the side panel to avoid dust.

prefer to close the case---looks better mah...seriously, if you have some fans blowing in air can close the case as airflow should be enough..what I have is a 120mm fan blowing in and when I close the case can fel air coming out from front and back so means hot air should be coming out...good enoughfor me I guess..tx

it depends on the owner and how long u are using the pc..
if u on pc 24/7 then better open for good air flow..
but if u already have good fan inside the casing no need open lar..

not true. If that is the case, then you should see servers running naked in the datacenter lor

well they are open because the ambient room temperature is so low with their powerful air conditioning.


not because of air flow.


even then they have good fans pulling in cool air to cool their server racks.


them high end racks are designed to dissipate heat efficiently.
