Is my GPU and CPU too hot? Do I need more fans?

[kenan.vad]

I recently bought a new prebuilt PC with I-8700 and GTX 1080, 16 GB's of ram and an SSD. But the case is a small case, with only 1 VER LOUD front intake fan. When I am browsing and dooing normal stuff, my GPU is 35 C and CPU is 40-45. But when gaming (PUBG ultra settings) my GPU is around 80 C and CPU is 75-80 C. Is this too much? Should I buy a bigger case with 2 fans (1 intake 1 exhaust). I don't want my PC to burn out

I don't think it's too much at the moment, but it's close.

It's higher than I would be happy with if it were my own rig.

So I would be doing something to cool it better....whether that meant a bigger case, more fans, CPU cooler...whatever...I'd be doing something.

....but I don't think your situation is anything imminent.

I agree with jay here...those temps are a TAD high, but nothing to worry about. Your GPU could easily be those temps because it's using a blower style cooler. Do you mind linking us the build/model of the PC?

Most modern cases have space for at least a 120mm fan at the rear, near the top of the case; putting a fan here to push air out of the case might improve both sets of temps, especially if the cpu fan also blows towards the new fan.

You dont state the size or rpm of the fitted fan, but "free" fans in budget cases arent of good quality or performance; think about buying a replacement when you go to buy a fan for the rear; a pair of 120mm Scythe gentle typhoon 2250rpm fans would give excellent airflow and are pretty damned quiet as well. Other quiet, good fans include Phantek and Noctua models; there are other makes, but these are the ones I have used or currently use and am very happy with.

I cannot send you the model, as it I have configured it, but I can tell you excactly what is in here and was cabinet.

Cabinet: Cooler Master Elite 342 with stock 120mm front intake

CPU: Intel Core i7-8700 3.20 GHz (stock cooler)

Motherboard: ASUS Prime H310 M-D

GPU: ASUS STRIX GTX 1080 A8G GAMING (blower style cooler)

RAM: Crucial Ballistix Sport 2x8GB 2400 Mhz

PSU: Shark Gaming Bloodpump 500W Bronze Certified (85+) (I have a 650 watts that I will put in it soon)

SSD: Kingston 480GB A400

You are good.
A intel cpu will slow down or throttle if it detects a dangerous temperature.
That is around 100c.
If you are under 85c. under load that is ok.

Graphics cards run hot but they are designed to do so.
They will target a max temperature like 80c. and run as fast as they can keeping that target temperature.
You are ok there.

If you want better cooling, the key is to get more air INTO your case.
Whatever comes in the front will exit SOMEWHERE, taking component heat with it.
Your front fan runs at 1200 rpm.
You can replace it with a higher rpm fan to generate more airflow.
Something in the 1700 rpm range would help, but at the cost of added noise.

Really, you need do nothing.

Thanks everyone. I am still a little worries by it running 80 degrees (i forgot to say that my CPU did peak at 92 at one point). I will take my old case and put my components in there, and then see if that is better (that case has both front and back fans) if the fans are not good enough, I will buy better fans. I know that the key is to put air into the PC, but I have also read alot of places that it is good to have a fan pushing out all of the hot air. Right now. I will do all of this in the following week or 2. Thank you for your input guys!

You picked some expensive , high end,hot running components & opted for a $30 case from 2007??

The elite 342 has awful airflow, it has a single,front intake which is 80% blocked off. by non removeable drive bays & a single 92mm exhaust mount.

Fine for a business,desktop with integrated graphics , not good enough for an i7 & a 1080.

I haven't had any experience of how important airflow is, because I haven't had this big of a PC before, so I didn't actually know. I have learn alot from this. No need to be aggressive

 

[jay32267]

For now, try running with the case open and see what happens.
I've gotten a lot of cooling at times doing this.

I will try that!
My old case is a Cooler Master Silenci 352. Will this be cabinet be okay to re use?

 

[madmatt30]

I didnt mean to come across as aggressive, just telling it like it is.
So apologies for that.

The silencio 352 is a way way better case.

You want a mininum of 120mm front intake fan & 120mm rear exhaust.
I would be inclined to add another fan personally so you have 2 x 120mm front intakes.

All good, no hard feelings. I will try that. Not sure if my old fans are good enough. But I'll look into buying some more. Thanks for the input

Hard to say....but as long as you can get things to fit it will be.
I'm not sure if you are talking about switching cases or what...but you can open the one you're using now and that might get you something.

I'll see if it fits. I'll have a friend of mine help me with everything on sunday. If it doesn't, I'll buy a new case, that has room for 3 fans (2 intake 1 exhaust). Then I will buy 3 good fans (either the ones I was suggested or I will watch some reviews) and then see. If it fits, I'll most likely just get some new fans and se if that helps.

I am glad you said I should try and run it open. I popped off the side, and now my GPU is MUCH cooler, and my CPU (on instensive games) runs at about 70-75. So it has helped alot, and by doing it, I am not in the ''danger zone'' anymore. Thanks alot!

If I figure out that I need a new case, the case must not exceed over 100 dollars if I need new fans with it too. Would the NZXT S340 be a good option?

I'm not real informed on specific cases....but the bigger the better.

...and I'm glad running with the panel off helped. It usually does. I do this a lot.

 

[geofelt]

Bigger is better if you need size to hold your parts.
Past that, it is all about airflow.

NZXT is a good case. It allows two front 120/140mm intake fans which will provide plenty of air.
One 120mm exhaust is all you need there.
The case comes with two 120mm fans.
I would keep one mounted in the rear as exhaust and relocate the top fan to the front and add a second front fan as intake.

That was excactly what I was thinking. We'll see if it can fit in the silencio. For now, I am just using open side for more air, and I only hit 80 in very CPU heavy games. Most other games I usually get below 70 with peaks of 77. I will keep your guys updated if you are interrested. Thanks

I have switched all of my component into my old Silencio case, didn't help much on CPU temp. I will buy a Be Quiet! Pure Rock cooler, along with a new case next week.
