so my computer is a dell, only changed the GPU and PSU and also heatsink, below are the specs

Case: Micro ATX dell case
mobo: dell mobo
Proc: i5 750
GPU: R9 270x
PSU: Corsair VS550

now i am still using my ori heatink, below are the temp
CPU idle: 48c
CPU Load:90c

GPU idle: 40c
GPU Load:75c

After changing cpu heatsink i expect the temperature for cpu to drop to
CPU Idle: 40c+
CPU Load:70c+

My current casing only has a 9cm exhaust fan at the back, and the GPU is about 7cm away from the bottom casing
and the casing I am looking forward to upgrading to is the Cooler Master CM690 III

Question is: Does it make much temperature difference if I upgrade to the CM690 III? since it has plenty of fan

If it helps to reduce the temp by 10c+ then i will surely upgrade it

idle 40*c+ / load 70*c+ is very normal for air cooler
which 3rd party cooler r u using now?

change case wont help. if u hv a budget of rm350 y not get something else? like ssd?

in my opinion, change case with a better air flow will help to reduce the temp. But, i cant say how much. Perhaps u can test your current case. just open the side panel and see how much the temp drop. and, did u apply the thermal paste correctly? i believe thermal paste also play some part to reduce the temp.

I agree. Proper heat/thermal paste application really gives a boost in temp reduction. My old rig used to hit 80+@full load, but after applying new coat of el-cheapo ones, not barely 70 @full load. Also, make sure all fans are clear of gunks...

I just changed to the CM Hyper TX3 few hours ago, and the temperature is as what i expected idle 40 and load 70.
the reason why i wanted to change case is because the side of the case gets really hot, so i was suspecting maybe air flow is the issue.
not planning on a ssd yet, coz its still expensive and after some time they will drop price, but a casing is an investment, after 3-5 years i still can use back the case


ok, i just tested, opening the case drop 2-3 degrees on idle (load not yet test)
yup, i applied correctly, one pea size then i use a card to smear it around uniformly

Ya, just cleaned it few weeks ago, its shiny now!

alright guys, seems like opening up the case solves the heat issue. i guess i will just stick with the same case for now

If your component temperature drops with opened computer case, this means the air flow in your computer case is not setup efficiently.
At least 2 fans for intake and 1 fan for exhaust. (Add 1 more fan for intake if you are using graphic card for gaming).

Note: The disadvantage with open case is dust will accumulate faster.

I am using the dell casing lol, there is only 1 exhaust fan and no intake fans.
Just checked, after one month of usage i can already see plenty of dust particles inside. So i think i will change the casing soon

Thx for reminding me about the dust, i never thought of changing the casing after the temp drop so much with the case open lol

If you have the budget, I would highly recommend you to consider Fractal Design Arc Midi R2 (RM370).
The Arc Series is optimized for cooling, whereas the Define Series is optimized for silence.
I owned both cases, and currently using the Define series, is very quiet (almost silent).

I have the budget since i got angpau money , haha. But then its still hard to decide whether to get an entry level case like the thermaltake h25 or cooler master n300 and use the remainder for ssd.
or my plan B is to buy the Phanteks enthoo pro. Full tower, pricing and specs also similar like the fractal design u mentioned.
Arghhhh , hard to decide

Hi, I am using CM 690 III... for me it's worth it... My specs are below , idle temp at normal room temp is 36-37c and 27-28c on aircond... i can say the front 200mm fan blows cool air (filtered) and they are cool.
I installed almost all fans except the one at the bottom... 1x jetflo 120mm (exhaust) , 2x Standard 120mm CM fan (top), and 1x Standard 120mm (hdd cage), and 1x 200mm (front)

Bro,before u plan to chanGE case. Make sure ur dell mobo is Normal matx tray. Almost of dell mobo is different back I/O and pcie slot (upside down).

For air flow = (position)3 air intake(don forget add air filter),1 air exhaust is may help a lot for cooling ur PC components and less dusty. It called positive air flow.

JaniceWLVSome inputs for low cost upgrade if it helps save your money:
- Assemble the TX3 fan as pull configuration.
- If the casing fan has grill, remove it. If you have to, cut it out.
- What is the ampere of the casing fan? Is it 0.17A or 0.23A? Look for something around 0.3~0.5A.
- If you open the case to cool the CPU, concern is that other critical parts like harddisk are not getting sufficient cooling. Reason being, computer casing is designed to have certain air flow for ALL components.
- Suggestion, instead of open side panel, make holes on the side panel. Focus on getting a few near the GPU, so that the intake of the GPU is getting fresh air from outside, through the side panel holes.

- For the GPU, does the hot air go out only through the rear casing, or also goes out at the front?
- If hot air comes out from the heatsink through both directions, then you will need an exhaust fan at the front of the casing. In this scenario, you'll have two exhaust fans.

- For the CPU, suggest you go to BIOS, and run the core voltage at slightly lower than stock. Reducing 0.125V or 0.25V for a CPU can reduce a lot of power consumption and heat.

I think u can get Phanteks enthoo pro M mid tower version now in Msia, lower price but only 2 3.5" HDD slot, 1 SSD slot.

u can put 3 front fan, remove the ODD cage if not using. then nothing obstruct airflow to your GPU, top can fit 3 fan also and got dust filter.

Hi there, thx for the comments everyone, for now i'll just stick with the same dell case with the side case open

Seems like a good idea to open more holes for fan.
But how do i cut through metal though ? Is dremel necessary or can i ust use a drill and attach cutting blades ?

Up to you.
If you have a drill, use a metal bit and back the panel on a solid piece of wood when you drill through.
If you want to use screw driver and a hammer, also can.
One forumer just used bullet holes, for real.

Open up the free CD-rom cover and put a small fan there(if it is near to your CPU.

post some pictures here. Maybe the case can be modded to add some fans. Eg, you said opening the side panel make it cooler. So maybe can cut a hole and add a fan at the side which make airflow better.
