Do bigger case improve/has better airflow?

[irfankamil]

My cpu (i7-7700k) reach 85c to 90c when gaming also my gpu (zotac 1080 ti amp extreme) reach 80c sometimes.

I will upgrade my cpu cooler (tx3 evo) to 212 evo. I'm currently using segotep k6 m-atx case and only have 3 cooling fans:

1. 120mm front x 2

2. 92mm back x 1

 

If I upgrade to bigger case that has more cooling fans mount, and upgrade to 212 evo, will it give huge temp improvement on my cpu and gpu?

Yes!

 

 

You can only put those 3 fans in your case?

you'll see bigger improvements for the gpu temps than the cpu with more airflow. The 7700k is a fairly warm cpu but it will improve with a better cooler & airflow

yes. 2 front (120mm) 1 back (92mm). top case just have some ventilation so no fan mounts.

IMHO The 212Evo is an okay air cooler.  It will ABSOLUTELY be better than stock.

 

No, case size is not indicative of airflow, or temperature improvements.  Case design, fan mount position, types of fans are.  If you have no other place to add exhaust or intake following the rules of thermal dynamics than perhaps you need a new case.  Id first make sure:

 

1.) My CPU and GPU heat sinks and fans were clean

2.) My front intake and rear exhaust fans were clean (and front intake unimpeded by case design, clogged filters etc)

3.) Check my Thermal Paste, that's a few year old CPU perhaps running in that rig

4.) Add more fans, specifically a bigger rear exhaust fan.

5.) Open up side of case first and game on, to determine that my temps improve and my case is the problem.

are the fans run at full speed?

i dont know. I think so since I just plugged it in without make any speed changes

any advise how to clean heat sinks?

Me?  I take a vacuum, 3 straws and duct tape:

 

1.) Tape three straws together, bendy types are best for reaching into areas

2.) Using the vacuums tool for edges I use duct tape to reduce it down to the size of three straws sucking in.  Yes it will cause the vacuum to "pop" its seal as the intake doesn't match what it needs.  From what I know this doesn't hurt a vacuum at all.

3.) Remove the items from the PC motherboard.  I do my Radiators not attached to the case at all.  I do my GPU heatsinks with them completely out of the PC and ensure I ground myself while using the vacuum.  I do not remove the heat sinks from the GPU's, I would remove your heat sink from your CPU and do it outside the case, and then reapply thermal paste and put it on.

 

Vacuums can build up static.  Someone here will probably tell you its dumb and will kill your PC parts.  Ill tell you Ive been doing this for 20 years and it hasn't killed a single thing yet.  Just make sure you are grounded.

 

Or, go buy some duster and spray the HELL out of everything lol.

Canned air works well.

It "works" but its nothing compared to a PC vacuum, or using an actual compressor.  I do all my rigs, laptops with the vacuum method I just listed.  Its cheap AF and works EXTREMELY well.  Just have to be smart about it.  Did my FX and Ryzen rig this last weekend....they look immaculate now.

No, bigger case does not guarantee better airflow. 

Open front panel, correctly placed and big enough ventilation chambers determine how much air can go in the case. 

Still, more fans can help with airflow. So can running your fans at higher RPM or replacing existing fans with better ones.

And I would you not to "upgrade" to 212 Evo, because all you do is replace a low end cooler with just a slightly better one
