Hi all.
I bought a new PC. Right now it used mostly for Office and some coding but there are plans for more work.
My current concern is with cooling. I installed World Community Grid that uses my CPU for fighting scary stuff like cancer. Well, i decided to let the program to run with 95% utilization on all CPUs and temps got high very quickly.

Here is my PC specs on CPU-Z website.
My enclosure is ANTEC P100.
Cooler: Acrtic Frezer Xtreeme rev2
PSU is Seasonic Focus 500Watts
Ambient temp is 26C or 78.8F.

Here are print screens of temp reading in HW-INFO v5.79

Well basically CPU shoots to 75C and VRM MOS is toasty at 91C.

My current idea is to install new case fans.
1. Install two fans in front of the case (replacing one Antec case fan).
2. Install one fan in back of the case (replacing one Antec case fan).
Also i can pop top panel and install two fans there (I presume it will increase noise from the case).

I prefer quiet fans. I thought about Nactua.

Hope to hear some suggestions and thoughts.
Maybe my temps are OK and i am too much thinking about it?

i don't think open the panel will improve things, if the air is trapped, then it's going to get hot regardless. i think you can try with intake fan first, it will increase the static pressure inside of the case a bit, and force some air movement inside the case, see if that improves the temp. i don't really have any recommendation on the particular fans, i just use w/e 120mm that's on sale.

Well....before I installed the fans....I would make sure my thermal paste was good and my cooler was installed correctly. That cooler looks like it should do a good job...so I'm a little surprised it isn't....but then again...you sound like you really are working the processor hard.

I would agree with Jay that cooler *should* be fine. Installing an extra case fan might help, I am currently using Noctua and they are great. What I am thinking might be the problem is the fact that since AMD runs hotter than intel that cooler might not be doing as well due to its lack of a fan. The tests on their website was tested with intel.

My regular temps are 40-50. But the fact that stressing the system brings it to 75C\167F CPU annoys me a bit, i was expecting more from the cooler.
Does 75C\167F is something to worry about?
Also the VRM MOS temp looks too high at 90C\194F, i just don't know if MOBO is designed for this kind of stress. VRM MOS temp is one of the reasons i thought about additional case fans. Arrghhh i should have bought a higher spec mobo.

This model do have a fan. On the official page, the photos don't show it. It's design is not so common. The fan is in the inside and not on the outside.
Just scroll to the gallery.
Here is a quick photo.

What Nactua model are you using?

B350 Mobo Usually have fairly weak vrm, I think the vrm heat issue is partially your cooler and partially poor air flow, looks like there is no air flow from these tower cooler, usually with the stock cooler, air get pushed against cpu then exit from the bottom fin, so vrm near the cpu gets some air flow, with tower cooler, that’s not there, I think you are in the right direction by adding 2 intake fan, you can add a extra exhaust fan on the rear top, but it’s up to you.

Unfortunately with 1700X you don't get the stock cooler.
What if i remove the panel and let it work without it for an hour during full load. If it will help, is it a sign that air flow is the culprit and i should get additional fans?
Do you have any recommendation for case fans?

Thanks for all the replies.
And for a funny story. I was looking at my HW Info fan read and see that graphic card's fans are not spinning. Until now i thought, yeah its probably some kind of silent mode and they will kick in when temp will get high such as in games. Then i did test on GPU with AIDA64 and still GPU's fans didn't spin. Now i got worried, what the heck. I remembered i installed some GPU's overclocking mambo jambo from Gigabyte (Auoros). So i went to the program that was running, and what do i see, a button that stops fans. I remember testing this two weeks ago i probably forgot to turn it on (Who needs this button except idiots like me?). So i pressed it and fans started spinning again (arhrhrhr, mother trucker). First thing i noticed that my SSD M2 drive temp dropped by 10-15C. Ohh great idiot, you were frying your SSD. Those M2 drives are on MOBO like a flee on a dog and it probably very close to GPU.
I will buy three brand new fans that can move air. Probably with PMW so i will have some control on them.

I don't remember exactly I am using a 30-50 dollar one I think (I didn't buy it, it was a gift.) on my fx-8350
