PC Overheating Issues, need help.

[Valhalla]

Hello,
I recently upgraded to Crossfire and its been great ( I can now do 4k). There is one major problem... My 2nd (Bottom one) is a 7870tahit and it gets real hot, it runs at ~90C and once it reaches around 92C it makes my PC crash and the screen gets black with random dirty white lines near the top and then shuts off, during this process the headphones make a terrible noise sounding like baaaaaa electronically. The 1st gpu 7950, is at a good temp. (77-85c) and does not make issues. Note all fans are on max rpm. What can I do to fix it?

 

Update:

The PC is even worse now... I opened the side panel and now its at 95c for both the cards and its a steady 95c. I upgraded my case from a bit fenix merc alpha to the aerocool extreme engine 3T that I got from a friend. Any help, I'm scared of using the PC now!

Also I play alot of BF4 on ultra 1080p 200% res. scale (4k).

Please help. 

Here are pictures of my current PC.

Power supply fan up or down? Temperature of the room? Total fans in the case?

Power supply fan up or down? Temperature of the room? Total fans in the case?

It's quite hot here in Vancouver, around 22-25c. I don't know about the power supply, there is one fan in the front and 2 on the side panel. The two fans are right next to each other and one takes air in and the other takes it out. Not sure if that's the best config. for them. 

Thanks for your reply .

First things first, do cable managment so the air can actually reach your graphics cards.  The next thing I would do is get some decent fans for the front, 1 airflow fan and 1 pressure fan.  To balance it out, get some decent fans and put them in there to bring in the air, the next thing you want to do make sure your graphics card's coolers aren't dusty, the last thing is to replace the thermal paste on the cards, because something graphics card's thermal paste can get all old and cracked and stops dissipating the heat as well causing super high temperatures.  Just get some decent thermal paste, if your cpu cooler came with a tube of it use that or grab some arctic silver or arctic cooling and use that.

no its not, have both fans push in because it can bring cold air to the graphics cards.

Might want to reconfigure fans and make sure power supply isnt sucking air out of your case.....

Use compressed air to blow out the dust from inside the cards.

Replace the thermal paste on the GPU coolers.

Dust your case and fans.

Use fan filters.

Have positive airflow.

 

If all fails, but a NZXT G10 and an AIO for both cards.

I don't know how to do cable management well. The front can only have 1 fan and its populated by the stock one there. Search up Aerocool extreme engine 3T. That's the case I'm using... I used to have the BitFenix Merc Alpha, and I THINK this one is better... I have Noctua thermal paste but won't it void my warranty?

 

Thanks

I don't have the money D:.

Dusting your entire case and doing cable management is free.

New TIM will cost <$10

TIM? And how can I cable manage?

 

Thanks

I wouldn't call the Bitfenix Merc Alpha -> Aerocool Extreme Engine 3T an upgrade.

Remove dust.

Configure the fans so the front fans are pulling air in, and rear fans is pulling air out.

Look at your power supply. One side will be flat. The other side will have a fan. Is the fan on the top or bottom of the power supply?

Tim=Thermal Interface Material. 

 

Cable managment is pretty much making every wire independant and not all clumped together.  Just unplug everything and redo it but this time making sure they arent tangled and using the other side of the case (behind the motherboard) to put your cables in order to have a clean flow of air from the front of the case, to your gpus and cpu and then out the back

 

It doesn't HAVE to look really clean, the most important thing is to not restrict airflow.

Bottom... The fans on the gpus are at 100%!

Okay, give me a minute to check.

Cable manage by neatly tying all the cables out of the way of airflow, zip tie them together to make it more neat, or tie them to parts of your case to keep them from moving in the way of airflow.

You should orient the side panel fans to take air in, the front fan to also take air in, and any rear fans to take air out. Those fans look pretty bad. You might want to upgrade those.

 

What is that CPU cooler? Looks awfully large to have one small fan on it.

These are the images of what I can do with cable management...

it's a very good one... Bequite Shadow Rock 2, a bit better than the H100... The cpu temp is fine.

[Valhalla]

Just something to add... 3 days ago, weather outside was 5c less, so less in the room, and the cards were 7870xt 83c and 7950 77c. 6 hours ago temps were 7870xt 92c and 7950 84c.

 

This is a dramatic change that I cannot explain! Any help?

[SkilledRebuilds]

Adding a fan to the HDD area pointed at/inbetween the GPU's for extra airflow intake.?

[daemonowner]

If the CPU cooler fan is pulling air through the CPU cooler, it may be taking a lot of the air pulled in through the front fans. And the side fans may not help bring air in for the lower graphics card.

 

The temperature difference you saw was because ambient temperatures matter. Opening windows may help.

Windows are open, The lower gpu might have some issues because of the fan not getting to it.
