GTX 970 STRIX having frame laggs/spikes

[Arumos]

Well my old computer was not good enugh to run most of the games that I wanted to play, so me and my brother built a new one. For the GPU we chose GTX 970 STRIX and it worked fine for a couple of months, but then for some reason it began to get some wierd frame drops and frame spikes and they're getting worse and worse. I've been doing reserch lately and I made sure that my fans are working propperly (heats up to about 45-50C) but my CPU is a differnet story (i7-4790K). I've downloaded Afterburner and Speedfan to set my fans on it to higher speed. Now Speedfan says its on 40C but Afterburner says its on 90-95C when I'm playing. I made sure that all my drivers are up to date with Driver booster. I still don't know whats causing the problem.

PS.:When I boost up the fnas on my GPU manualy the frame spikes arent as bad as if I would let them automaticly set their own speed.

Sorry for bad english, please help me.

Are you talking about CPU or GPU temps in afterburner?

What CPU cooler are you using?

what motherboard do you have? Do you have stock CPU heatsink?

you could use Asus GPU Tweak and set a fan profile to always be running - the default is it starts at 40C, I do that in summer to keep PC case a little coller

CPU
I'm using the deafult cooler that came with it. IDK how to check. sorry I'm new to this computer stuff...

You'll definitely want to pick up an aftermarket CPU cooler, sounds like thermal throttling to me.
Download CPU-Z and GPU-Z and check temperatures under gaming load, and load percentage.

Yeah sounds like the CPU is throttling due to high temps.

GPU at about 40C all the time
CPU 70C rigth now (goes up to 95C) when I'm playing

CPU temps are definitely the issue.
What country do you live in and what retailers are you using?
I'll select a few coolers for you. 😉

I'm in Slovenia

some retailers i know are:
-Comshop
-BigBang
-Dinokomp

(I ordered all the components fror my compuer from Dinokomp)

To obtain temperatures that high, even with the stock cooler it shouln´t happen. I´ts definitely Thermal Trotting. Probably due to your thermal Paste being badly applied or simply Dry.

If you wan´t a really goof cheap Aftermarket cooler Get the Evo 212
If you can afford and it FITS in your case Take an used Noctua NH-D14 or a NH-D15 (if it fits your case, And motherboard)

I do remember that when the cooler was put in, that we took off the fan for about 5 secs. Didn't think it would matter but still. Should 5 seconds realy make a difference?

Definetly will check if the paste is applied correctly or if it's dry.

Though there is something bothering me. SpeedFan says that the CPU temp is around 40C. And when I set my GPU fans to 100% and the GPU cools down, the frame spikes don't have as mutch effect, but the difference isn't very big. In the case that the thermal paste was badly applied, should this realy happen?

Depending how you apply the thermal Paste it could really cause bad consequences, too little and the CPU - Heatsink wont habe optimal contact temperature will rise, too much, and it makes the opposite effect insulator which can Dramatically raise your temps. Iits not a bad idea to replace the thermal paste and check if your problem really is there

Reapplied thermal paste. Turns out that the amont of thermal paste on the cpu cooler that came with the processor wasnt enugh. Thank you all for helping me solve the problem, I realy appriciate it
