First Build Ever, are these normal 7700k temps?

kev7ovo · Sep 4, 2017

Hi guys, first time poster.
Just built first pc:
CPU: i7 7700k (STOCK)
Mobo: Asus - PRIME Z270AR
CPU Cooler: Cryorig H7
GPU: Asus Strix GTX 1080
Case: NZXT S340 Elite
Ram: G.Skill - Trident Z RGB 16GB (2 x 8GB) DDR4-3000
PSU: EVGA - 650W 80+ Gold Certified Semi-Modular ATX Power Supply

Just did some benchmarking with Prime95, my CPU reached temps of 97, but I found out it was because I was using the wrong version. Now, they reach around 82c (which I believe is OK?). Thing is, with XMP enabled, they reach 86-87? Is that normal? Also, the only game I currently have is Rocket League and while playing, looks like it maxes out at 78c. Seems kinda high for such a basic game but I have no idea what is normal for a 3 fan setup (2 that came with the case, 1 cpu fan). I don't know if my voltage is too high or what. Disabling XMP also dropped about 8-9 degrees while playing Rocket League as it used to max out at around 87c.

Here is a pic of CPU temps just after gaming: https://imgur.com/a/Qyaf5

My VID voltage while running Prime95 at 100% load is 1.254 (is this normal)?

Thank you all!!

82C in p95 is just fine for that cooler.

If enabling the XMP is causing overheating it is likely b/c your CPU cooler is sucking hot AF air off of the DIMMs. While gaming, inadequate air flow will also cause the internal temp of the case to get quite high.

I suspect that you need to upgrade your case fan situation.

I appreciate the response! Ok cool, thats reassuring. I believe the s340 elite has 1 intake and 1 exhaust, the exhaust being in the back and the intake being on top. I really cant tell though, its hard to feel. I think that if I add 2 intakes at the front of the case, temps would improve. Im curious by how much approximately though?
Also, I am curious if my gaming temps are normal? If there is a free CPU intensive game to test on maybe then I could see if they get any worse than 78c.

HamBown81 · Sep 4, 2017

It has one of these in the front and one in the back https://www.nzxt.com/products/fn-v2

That is NOT nearly enough airflow for your components. Only 45CFM

EDIT: I realized that there is NOT any fans on the front...

HamBown81 · Sep 4, 2017

Fan Support
Front: 2x 140/2x120mm
Top: 1x 140/120mm (1 x 120mm FN V2 Fans Included)
Rear: 1x 120mm (1 x 120mm FN V2 Fan Included)

Radiator Support
Front 2 x 140 or 2 x 120mm
Rear 1 x 120mm

I would look at completely replacing your stock fans with 2x140mm in the front and a high CFM 120mm in the rear.

EDIT: In the meantime, I would move the fan that is on the top to the lower front position. This will make a big difference, but it is not enough.

HamBown81 · Sep 4, 2017

The design of that case assumes that you are going to have an AIO on your CPU and put the radiator at the front.

You essentially have NO intake fans right now.

kev7ovo · Sep 4, 2017

HamBown81 :

Yes, those are them! But mine has one in the back and top, not any in the front. Do you have any fan suggestions? Should I get 2 120mm or 2 140mm for front intakes?

HamBown81 · Sep 4, 2017

HamBown81 :

I edited and added some stuff to my previous post(s)

kev7ovo · Sep 4, 2017

HamBown81 :

Ah haa, just saw them all pop up after replying to it. So you suggest removing the 2 stock fans totally, replacing them with CFM120s, then getting 2 140s for front intakes?

HamBown81 · Sep 4, 2017

HamBown81 :

I would suggest something like these at the front

And something like this at the rear
https://www.newegg.com/Product/Product.aspx?Item=N82E16835103193&cm_re=120mm_fan-_-35-103-193-_-Product

You could leave one of your stock fans as a top exhaust and save the other one.

HamBown81 · Sep 4, 2017

Down the road, if you get brave and decide to OC, that cooler may not be enough either.

I have the big brother CRYORIG R1 Ultimate, which would be up to that task.

kev7ovo · Sep 4, 2017

So i'm kinda lost when It comes to fans. I understand there is static pressure and air flow, which would be better for my setup? Also, I am not sure how fans are controlled. Does my mobo have enough fan headers plugs? And how do I make a fan exhaust/intake? Can any fan be either or?

Heres a pic of my build: https://imgur.com/a/i4Poi

Thank you for all the help

Static pressure fans are "stronger". Normally they are good for radiators or for use in other restricted situations, like a closed front. https://www.kitguru.net/components/cooling/dominic-moass/static-pressure-vs-airflow-fans-is-there-a-real-difference/

Fans are intake or exhaust based on the direction they are facing. https://www.howtogeek.com/303078/how-to-manage-your-pcs-fans-for-optimal-airflow-and-cooling/

Your motherboard has lots of fan headers, they are explained in the manual.

I would suggest getting a splitter like this and running the front intake fans both off of header CHA_FAN1

I would connect the high flow exhaust fan to the H_AMP_FAN header

If you keep a stock fan on the top, you could connect it to the second CPU fan header as it is closest. Honestly, I don't know if I would bother with this. Is there a panel that closes-up the top if you want to?

BTW, that is absolutely gorgeous. I am totally jealous.

HamBown81 · Sep 4, 2017

Until such time as you can get some fans.... do this.

HamBown81 · Sep 4, 2017

Make sure that the side of the fan which is pointing up right now is facing inside the case. Normally the intake side is the "pretty" side of the fan.

kev7ovo · Sep 4, 2017

HamBown81 :

Dude! Never have I had such a pleasant experience on a forum, thank you so much.
Because I'm on a slight budget, and I am by no way a fan expert, I think I may just get two intakes at the front, and keep the two stock fans in the back. Now that I feel them, I believe they are both exhaust fans. I don't see anywhere online that says what they are but I can feel air being pushed outwards. Because I have no radiator, and my case has space in the front for intake, would you suggest 2 140AF fans? or static? And the splitter is genius. Never knew those existed.

On a side note, thank you for the compliment! Very proud of it hah, yours looks dope too

HamBown81 · Sep 4, 2017

These are good ones, not too expensive and match your stormtrooper theme. There are lots of choices.

EDIT: You don't have to worry about SP fans. Removing that dust filter from the front is a good idea when you are gaming though. That is what I normally do and then replace it when I am done.

madmatt30 · Sep 4, 2017

Good advice from hambrown above .
I dont agree on removing the filter in use though.
With 2x140mm intakes you'll have great airflow even with the filter.

Re - the a.c. f14 fans , a good budget choice - the pst version actually has splitters built into the cables though so no need for a separate splitter at all.

Removing the front filter in my Fractal Define R5 makes a noticeable difference to the torque on the intake fans, especially when the door is closed.

Less stress, better airflow. I am not concerned about the extra dust, I clean regularly and have the filters on when I'm not in a long gaming session.

Just a suggestion either way.

I'll try both ways perhaps, and I found these, the leds caught my attention haha. Will they do for my needs?

HamBown81 · Sep 4, 2017

madmatt30 :

For sure

madmatt30 · Sep 4, 2017

Big difference between the r5 & s340 though when it comes to removing filters.

Youre spoilt with the r5 when it simply unclips from the front easily. The s340 you have to remove the front bezel.

HamBown81 · Sep 4, 2017

madmatt30 :

Ahhh, yes. I just have to open the door.

The bottom filter slides out the front too

kev7ovo · Sep 5, 2017

HamBown81 :

Sorry to revive this thread, however I thought of one other question that may, in the end, help others too. If I buy these, and plug them into CHAFAN1 and CHAFAN2, does my bios automatically adjust the fan speeds according to load/temperature? Thanks!!

HamBown81 · Sep 5, 2017

madmatt30 :

Yes, it will, but it is not always the best at it. The reason I suggested using a splitter is so that both intake fans are in sync with each other, I don't know how much that matters.

If you are having temperature issues you can use the BIOS Q-fan controls or ASUS FanXpert to change the fan profile. If you want to fully customize you fans response to the temps of individual components, you can use something like SpeedFan

First Build Ever, are these normal 7700k temps?
