Still having cooling issues... help please

Hi guys, I have drawn a layout of my current PC interior (fan direction etc)

I am currently having problems with a hot hard drive (50-60c), GPU's are reaching 70c under load and system temp is reaching 50c+.

caselayout.gif


Blue Box = 92mm Fan
Red Box = 120mm Fan
Blue Arrow = Air flow direction

Does anyone have any solutions to overcome my problems? My side window for the VA8000BWS does not have a fan. One idea i was having is maybe 4 x 120mm fans blowing inwards onto mobo gpus?

Let me know your thoughts :)

Thanks in advance.

Can you not mount the hard drive lower down, between the 2 fans on the front? At the moment the air coming in will just miss it and the 92mm one on top is just going to be blowing hot air over it, theres no cool air coming in to feed that fan.
 
I will look into that, another idea was mounting 2 more 120mm fans above the front one and moving the hard drive behind it. I just need to find a good method to fit them there as there is nothing to screw them into.
 
Yea, that should improve it a bit. Anything really that puts the HDD in the path of cool air i.e. air coming from outside the case should help
 
Is the 4 120mm fans in side panel a good idea? Baring in mind that it would cost £40/50 if i use noctua fans or something.
 
they will help reduce your system and graphics temps by how much will depend on wether you have them drawing cool air into the system or exhasting warm air out
 
Hi rexehuk

Looking at your PC layout i would look at something like a CoolIT Domino ALC!
It would help with yrou thermals.

Basically, install a Domino and because of the way it works it extracts teh heat directly away form your CPU and out teh back of your case, working cooling this way it will bring down your overall chassis ambient temprature :D Thus helping with the rest of your components. Add in a 120mm case fan for additional air flow and you will then have a nice setup :D

So in short, Having heat extracted from source, striaght out of the chassis and then bringing in cool air you should have a nice flow.

Just my two pence worth :)
 
Hey thanks for your reply, appreciated that you took your time to look :)

I have another thread going in the case section. I don't know if I can use the coolit domino, the cpu cooler is brand new and it would be a £60 writeoff. People have recommended me a Coolermaster CM-690, do you think this will be a good investment?
 
Never understood why people buy noctua fans, there vastly overpriced for the very extreme minimal of what 2 less db?

£5 Xilence fans do it for me, not a big brand but price : performance is unbeatable.
120mm - 68cfm - 21db.
 
Avoid the Coolit Domino; it's not very good and certainly not worth the cash over what you have.

Stick the HDD in the middle of the fans; that way it disrupts airflow as little as possible, but still has air going over it.

4890s loading in the 70s is nothing to worry about at all; they are good up to 85 tbh.

System temp of 50c isn't all that bad either.....your CPU load temps are the most important - what are those?

Agreed, so why not use a Domino to get the heat away from your CPU and out of the case? two birds with one stone.........Cooler CPU and Lower Ambient case temp......?
 
Fan blowing down onto hard drive is doing nothing but harm. I vote for getting more air into the case, but preferably not through the side. Can you mount intake fans in the 5 1/4" bays?

Step beyond that is reverse the direction of the top fan. I will tease the first person to tell me that this is going against the laws of physics, try it and see.

If going for considerable effort, which is sounds like you might be, I would:
Reverse direction of top fan, have it blowing inwards
Remove the fan currently blowing downwards onto the hard drive
Fit one, or if space two 120mm fans as intake in the drive bays. Suspend hard drives behind these.
Remove the fan behind the one at the bottom, front.

Coolit domino is not a good shout, -1 for that. Properly water cooling would indeed solve the temperature problems, but would not be cheap, quick or easy. Reflux makes a good point in that your temps don't look so horrific besides the hard drive, which is starting to push your luck a bit.

Primarily because it doesn't work very well. A massive heatsink with a fan on it blowing hot air straight out of the case is a similar idea conceptually, except that it works better. The coolit system is an interesting idea which does not perform well enough to justify the price or replacing the current cooler.
It also does a rather poor job of cooling either graphics cards or hard drives.

Most likely more heat is coming from the 4890s. I've had two, and they are warm, warm cards. The Domino might clear heat out of the case more effectively than a traditional air cooler, but it's a lot of money for something that doesn't really do its primary job - cooling the CPU - as well as it should for the price.

I don't think his system temps are bad, with that amount of high-end hardware in there.
 
From layout and those couple fans I'll take it that case is "Thermaltrap"...
If that's the case start by removing those stamped El Cheapo plates blocking exhaust fans.

Agreed i have seen worse lol :p

Definitely need to cool them VGA cards down, Hottest thing you have in your system, if you are looking to get lower

Exactly what I was planning to do.. not remove plates but drill them out to make the vent holes a lot bigger, sound ok?

Side fans blowing cooler air onto the GPUs sounds like a good soloution. What mounting options do you have?

Mounting options... what ever really. I was going to go to B&Q to buy some mesh, make some sort of mesh window for the side after cutting a hole out of it, then fitting a couple of fans blowing directly onto GPU's. For the front... don't have many ideas how to mount fans atm. I was considering making 2 rails from top to bottom which I can then screw fans into.

Hard Drive Temps - 55c (towards the end of the day)
System Temp - 50-55C
CPU - 40C Idle - 50C Load
GPU - 45C Idle - 65-70C Load

Oh.. and thanks for all your replies :D
 
Also if this plan is going to work, the fans need to come to like £20/30 max for 5 120mm's. Otherwise it makes more sense to me to buy the coolermaster case for £50

Hard disk is warm as has been said, but nothing else is anything to worry about. My i7 loads at 78c; granted, it's heavily overclocked, but that's not hot enough to bother me. System temps must be 40-50, and my single 260 loads at 75c in some games.
