Looking for Suggestions to better cool my PC

Whats up guys new to the forum and to over clocking here.

I just build my pc about 3 months or so ago (specs in signature) the most recent change that i have done to it is added a second MSI R9 290X card and set them up in Crossfire 190 FPS on benchmark pretty dope lol

but i wanted to experiment with over clocking the CPU......cranked it to 4.6 GHz and with 8 mins into a Prime 95 stress test.....CPU temp reached 65 Centigrade on the socket 48 Centigrade on the core so i backed it off tried something simple like 4.3 GHz and withing 11 minutes into the stress test again spiked to 65 Centigrade so right there i backed off and defaulted the BIOS and CPU back to 4.0 GHz

Right now I have the Corsair H110 Liquid cooler on the top of the case with the fans on the bottom of the rad pushing air out.....had them pulling air in but wanted to experiment with them pushing air out see if that helped (don't think so) the rear fan is pushing air out.......the 2 front fans are pulling air in.....all the fans right now are stock fans.....I really want to experiment with over clocking I believe that everyone in computers whether you agree with it or not should know how to do it....but not with these temps......I was thinking of replacing all the fans on the pc and also move the HDD cradles to the top under the 5.25 inch bays and on the bottom add 2 more fans pulling air in from the bottom changing the front wall fans to push air the rad fans back to pull on top of the rad and leave the rear fan as exhaust.

Any thoughts? or am i gonna have to custom close loop liquid cool the machine.

Thats what the machine looks like right now

Thanks guys for the help

few suggestions.
1. Take off your side panel
2. Put a fan that can push air directly between the two GPUs, where the fan is right in front of the grommets (your GPUs are supplying hot air to your CPU, so if you can cool down your GPUs, you in turn cool down your CPU) e) we did this with a Scythe 3k rpm fan while we had our 780's in SLI and we got a 10C reduction.
3. Higher flow fans?

Thanks for the tips Skye
yes that is one of the things i don't like about this case......no place for a side fan......i guess its the trade off for the window....definitely gotta change the fans though no doubt.

when it was at 4.6 GHz i dont remember exactly but i do remember that when it was going like that the CPU started drawing 1.38 Volts so the VCore got to 80C and the computer threw a warning which is why i backed it off......i was trying to find the highest OC i could get with default voltages and be stable.....probably was doing it wrong who knows....part of the learning process......i backed it off because i know the limits are like 70C on the socket 60C on the core something like that.

I wouldn't suggest anything over 2k rpm, as the noise can get annoying.
I've never truly used a fan on the side of the case because I just hate the sight of one there.
But I would almost suggest a decent flowing fan (~2k) pushing air towards the cards that close. Only takes a few cable ties and will help out until you figure out what you want to do.

OK - I need to circle the wagons and make sure I'm not confused. Are you concerned with your processor temps or your GPU temps?

CPU temp from what I take it.
The heat from the GPUs increase the CPUs temperature. Heat rises.

I agree with you.....i think my strategy is making sence then.......2 fans pull air in from the bottom while the 2 fans push air right to the GPUs.....hell the front wall fans are trying to suck air in when they have a filter and a front panel that does not allow much air through might as well make them push air then.....what do you think

Just wanted to make sure, though I wouldn't expect to see that high of a socket temp from GPU usage.

My suggestions / questions:

Did this start only after you added the second card?
Do you have the latest motherboard BIOS (I've heard of false temp readings because of outdated BIOS)?
When overclocking - do you have your processor set to consume a constant voltage or are you using Adaptive?

You could try it but I don't think it would be enough,

right now CPU temps......the video cards have not complained......only one time because i had the case fans in silence.....experimenting but then changed them to standard......using the asus AI tools to control the fans

He has two 290x's
These things produce a lot of heat, I could easily see them being in the 70's and 80's, of which is going up to the CPU rad

I started experimenting.....after i added the second card.....i checked for latest bios updates before trying this and it said there were no bios updates.....when i tried it....i manually set the voltage but isnt there are a settings CPU load line calibration i think that feeds extra voltage as the load increases to keep the cpu stable?

the only time the second card fans kick on is when i run a game or something like heavens dx11 benchmark test....in plain desktop the top card fans are on only the second card turns off its fans
 
#17 ·
would seeing temps help? let me know i'll post temp picks.....but only on stock cpu clock i wont over clock it

Which means that the card can safely dissipate around 50 watts of heat into the case, I'd say make it always blow heat out.
 
#19 ·
yeah these cards are not AMD reference config so the fans only blow down to the heat sink and not out.....at least i think

That's normal for AMD cards - when you're in a 2D application the second card essentially shuts down to conserve power. Once you enter a 3D application it starts back up and the fans begin spinning.

Yes - I would like to see temps in a stock configuration. Just for laughs, could you also post temps of your GPUs during the test also?
 
#21 ·
Ok so i just got in and took these temps

Idle


heavens dx 11 windowed 1024x768 on high


and prime 95 for about 15 mins stress (dunno why prime is not stressing the CPU to 100% load


I was looking at fans today.....still surprise there is a noctua fan that costs 70 dollars thats crazy

there you go for laughs

I wouldn't recommend going custom water cooling unless you plan on spending 300 dollars or more. Plus it's almost immobile. My case now only move at most 1-2 feet max. Anything more and I need a second person as well as towelling the inside in case of water leaks. I went from an AIO to a custom loop a two years ago and the difference during summer is only about 5-10c. Like right now just openning the window I get more cooling done than any of my radiators can do, thanks old man winter!

I had a Kraken X60 and I hit 4.6-4.8ghz on it. On my custom I don't even stress/OC as I used too. Random restarts and wear really stopped me from OC'ing more than 4.4 which is stable for 24/7 gaming. Also all this less noise is a lie. Thanks YTers, you need like extra 2-3 more radiators just to lower fan noise, etc.. I have 14+ fans, two 3x120 radiator and a 3x140 radiator and it's just a tad better than my x60 kraken so yea. Nothing like phase changers and TEC cooling.

So you truly believe that if two identical computers were compared temp wise, if one had one or even two GPUs and the other didn't have one, that the CPU temps would be the same?
I'd easily have to disagree.
The GPUs don't heat up the CPU directly, warmer air goes across/is used to 'cool' the CPU.

So you think it's a little hot too right? I just opened the machine up and changing the rad fans back to In take might as well look at the thermal while I'm at it. Now where is that alcohol
