Is this cooler suitable for my CPU and Case?
Hi guys,

I currently have an i5-9400f and the stock cooler is not sufficient for good cooling. This is why I was looking into other air cooling options. I ran into the cooler by CM called the Hyper 212 which seems to have a lot of good reviews. I was wondering if this cooler would be sufficient for my CPU. I mostly just do gaming on the PC. Also another question I have is my case says it can support CPU coolers upto 160mm and the hyper212 website says the height of the cooler is 158.8mm. I know it numerically means I can use the cooler, but since there is only 1.2mm difference between the max and the actual height will this cause any issues when i try use this cooler in my case?

Here are the links for both items:

QwerkyPengwen January 16, 2014
QVL is just a list of RAM that was physically tested by the motherboard manufacturer and is only a list of such.

And they only typically test slightly higher tier RAM and don't bother testing bottom of the barrel budget RAM, but all they test for is if it will run at rated overclock speeds and timings (anything above 2400MHz is overclocked)

The RAM will work, but worst case scenario is that it won't run at speeds higher than 2400MHz but since this is an Asus board you should be fine cuz Asus has fantastic RAM compatibility, and G.Skill makes good RAM even on the budget end.

Dont know what to pick between these 3 specs
Morning everyone, first time being here, but heard is a good place to ask stuff.
So, as the title says, i have to choose between these 3 specs:
Spec number 1:
CPU: AMD Ryzen 5 3600X 3.8 Ghz
GPU: GTX 1660 Ti
16GB RAM DDR4 3200 Mhz
512 GB SSD
MOBO: AMD B450
Spec number 2:
CPU: I5-10400F 2.9 Ghz
GPU: NVIDIA GeForce GTX 1660 Super 6GB
16 GB RAM DDR4 2400 MHz
HDD 1Tb + SSD 256 GB
MOBO: H410
Spec number 3:
CPU: Intel Core i5-9400F 2.9 GHz
GPU: NVIDIA GeForce GTX 1660 Ti 6GB
16 GB RAM DDR4 2666 Mhz
SSD 512 GB
MOBO: B360 intel

I have to mention that my intention is to buy a PC just for gaming and watching stuff online (so no programming, no multitasking). Some friends told me to buy the rig with amd cpu, but arent amd cpus overheating at some point, or being way hotter than intel cpus? If yes, how can i avoid it?
Please use arguments when answer this. Thanks a lot!

Spec number one, however if you can I would change 1 to a GTX1660 super as it is lower price and basically the same as a GTX1660ti. The Ryzen 5 3600x I would change to a regular 3600 as you don't need too much of the power and you can overclock a stock one to the same speed as the 3600x. The RAM is 3200mhz which is the best choice for ryzen and is very fast, check videos on youtube to see how much more fps you get. Unless you are going to install a ton of games, the 500gb ssd is a great choice and the mobo is cheap and affordable. So spec number 1 by a long shot.

Low FPS on The Forest on 1366x768 resolution while on high and low settings
The performance im getting while playing The Forest keeps on bugging me as I always experience FPS drops and frequent stutters which ruins my encounters with cannibals in the game.

Here is my specs:
R7 1700
RX 570
16GB RAM
320GB HDD
240GB SSD (The forest is installed here)

The performance im getting is a whole lot different than my brother's, since the only difference on our PC is just that he is playing on 1080p, his processor is an i5 9400F, his playing the game on an HDD, and his RAM is 8GB. He's also playing the game with me while he's streaming, while I am not streaming at all. He never experience fps drops and I can also see that his game is running much smoother than mine since we play side by side literally.

So I have no single idea why am I getting this kind of performance since I am playing on a much lower resolution than him, lowering the settings to their lowest does not make the stuttering and fps drop go away at all.

Or should I conclude that the game is not optimized at all for AMD processors?

Note: Sorry for my English it's not my native language.

CPU: i7-9700k
Mobo: Asus MPG z390 gaming plus
PSU: gamemax 800w atx power supply
GPU: MSI RTX 2060 SUPER

I believe I have enough power to support the i7 and the rest of the build given this i7 doesn't draw significantly more power than my previous i5-9400F. I'm just not sure what is causing the issue.

Struggling to pick a CPU
I’m having some trouble picking out what cpu I should pick. An I5 9400f or an AMD Ryzen 5 1600AF. I mostly play games and edit videos and I want the cpu to be balanced. Great for productivity and great for gaming too. Any help would be greatly appreciated.
C
cdrkf March 18, 2013
That is easy, the 1600AF has twice the threads so will be much better for productivity whilst still being decent for games (especially if paired with fast DDR4 memory, which you cannot use with the i5 unless you pair it with a very expensive Z series motherboard).

Do I need to update my Bios? I have a ASRock B360M Xtreme.
When I check the compatibility to upgrade my i5 9400f to i7 9700k, says that "Some Intel B360 chipset motherboards may need a BIOS update prior to using Coffee Lake Refresh CPUs. Upgrading the BIOS may require a different CPU that is supported by older BIOS revisions". BUT my version is a P4.00 dated 03/19/2019.

The 9400f is rated for up to 4.1GHz stock from the factory, what you are doing is perfectly safe, wont impact lifespan, and is a part of the design.

High temps with gtx 1660
Hello, everyone

I got myself a new build about 5 months ago. It's got a I5 9400F + asus phoenix OC gtx1660 + 8gb ram.

The machine is performing greatly. 60fps+ on every game with high-ultra settings. The only issue being the GPU temps while under load.

The case has all of its 3 fans on the front panel. I have no fans on the top, neither on the back.

I had no idea the temps were this high with certain games.

Apparently Witcher 3 has been killing my card. Looking up Msi afterburner while playing, I've come to notice that for most games, the fan finds itself at 59%. Would turning it up or messing with the fan curve solve it? I'm a bit of a noob and have never done it before. Is it safe to mess with the fan speed slider on msi afterburner? I guess I could add an extra case cooler or get an aftermarket cooler for the card as well.

Below are some screenshots with my current temps:

View: https://imgur.com/a/NPJKl8S


I removed the case's side panel and the overall temps dropped about 10°. I went from an average of 78° on gta to 66-67°, for instance.
R
Ralsei October 01, 2018
In a case like that I would invest in more exhaust fans than intakes... move one of the intakes to the back as an exhaust and see if that helps.

Stuck on sizing and compability for CPU cooler
Recently I've been slowly replacing all the parts of a pre built computer I bought a couple years ago and currently it has a small coolermaster CPU fan installed I'm not sure of the exact name it just looks like a basic black CPU fan. This is the last piece I need to replace but I'm worried I might buy something that isn't compatible or won't fit because my case is pretty small.

So my question is which one of these (if any) will be fine compatibility and space wise?
