CPU Cooler - Akasa AK-925 REVO Thermodynamic Core2Quad Cpu Cooler
http://www.scan.co.uk/Products/Pro [...] tID=685716 - NOTE - Must be facing upwards towards the PSU or to the RIGHT for this to work, I have tried facing towards the left (directly facing the outtake fan, but after some reading found this could damage the mechanism used, as it uses gracity to let the liquid flow to the CPU)
CPU 1 - 25DC, CPU 2 - 35 DC ~ IDLE
CPU 1 - 30DC, CPU 2 - >40+ ~ LOAD (gaming etc)
HI I have made a very colourful diagram to help describe my problem, the diagram to the left shows how it currently is with my case. The temps are pretty high dont you think? near the HD's its like Ice cold, but near the CPU its so hot I am probably heating my room with this warm air. The PC P&C Fan etc doesnt help to remove the heat either , I have tried to make the diagram look as accurate as possible and so as you can see the PSU takes air from the case and uses that to cool the PSU then blows it out the back (correct me if im wrong), but as the PSU back end is at the top of the case the hot air from CPU is being blown into the PSU, I dont think the air comming from the front reaches this far to help aid cooling CPU/PSU/RAM - it is most likely being sucked in by the GFX cards fan and then blown back down the case.
So Im planning on getting a 120mm side fan (as shown on the right hand side diagram), will placing it directly above the RAM help to improve cooling? what solutions would you suggest? My Powercolor is faulty and on monday it will be collected as part of RMA, hopefully by Tuesday they will have agreed the refund, then I can order the new HIS IceQ 3 Turbo 3870. This will then help to improve the air flow with the lower end of the case? Cool air comes in from the front intake and passes HD's etc then is sucked in by the IceQ 3's Cooler/Fan to be pushed out of the back.
I ran out of the original compound provided with my CPU cooler (akasa something) and then used some MX-1 I had from last year but I think this was messed up as it was rock solid and didnt do the job, so Iv bought some generic compound from local PC store to keep it going till I get the new graphics card and also ordered 120mm fan plus MX-2.
Fan I plan to order next week -
AcoustiFan DustProof Quiet 120mm Fan - 3 pin - http://www.overclockers.co.uk/show [...] 7&subcat=4 - with setting it at - 7v: 41.5 CFM, <15.6 dB(A), 1050 RPM
Will this do the trick? enough Air comming in and noise level is very important, my comp is near silent except for the regretful WD raptors I have they are very loud.
Also getting this to make sure CPU is cleaned properly -
ArctiClean Thermal Material Remover and Surface Purifier - 60ml Kit

Any/All help/suggestions welcome
Thanks in advance (even if you aint going to post atleast for taking time to read it)
Forgot to mention 1 major issue with this case, I can get the side panel for it but it doesnt have any holes already made for adding a side fan, so if you know anywhere I can buy such a side panel that will fit this case and have the fan where I have descriped please can you let me know, Im currently thinking of having to drill four holes for the fan and maybe either cut a circular hole or make smaller holes in a circular pattern covering the 120mm circle.
Does it have any vent holes on side of case if so with a zalman FB123 fan bracket mounted low on add in card slots you can get a fan close enough to draw air in from the side. It worked great for my case and cooling my 8800gt, just a thought before you got to take tools to your case.
Your cpu temperatures do not seem out of line to me. If the cpu gets too hot, it will throttle itself to stop any damage.
The new vga card will help you a lot because it sends the hot vga air out the back of the case instead of letting it recirculate.
I would replace the cpu cooler with one that directs the hot air towards the rear exhaust fan. As it is now, you are making the psu work harder. The fan on the psu is there to protect itself from heat, not to cool the case.
A single 120mm output is now matched with a single 120mm input fan. Adding a 120mm input side fan would provide more input, but would disrupt the straight through flow you now have.

Hi thanks for the reply, there are no vent holes on this case, its rock solid shut, only front for the intake and rear for the outtake, please check the link for the case. I found a side panel with side vent directly above the graphics card, but i know my graphics card has sufficient coolin so i dont need any more air/fans around there.

So your saying that with the overall temp being 60DC this is normal?
I just bought this comp about 2 months ago, that akasa cpu cooler im using - weird but - looks like the bizz but if I have to replace it what HS & F would you suggest? Most forums say something along the lines of a TT (something something) HS and then a sep 120mm fan, this cpu cooler runs around 2200rpm and I cant hear it. But I think you may be right and so Im planning on getting a replacement later on if problems still persist after installing a side fan. What CPU heatsink & fan?
I dont think its straight forward flow from intake to exhaust, Im guessing 70%~80% is being sucked in by the GFX's cooler/fan and will still do with new GFX, so that leaves 20%~30%max to cool the CPU/RAM/PSU and any other components situated above the GFX. This doesnt seem like the best air flow, if I were to use the new side fan and have it above the ram this would atleast add more (cool/room air) for cooling CPU/RAM/PSU etc.
I saw the temps on it, it seems to run a lil better then a stock HSF. (they were using E6850)
I'd say the airflow is prolly not as good as it could be, that you'd have some kind of vacuum lock with the exhaust and CPU fan, though it seems you can only install it with the fan pushing air up into the PSU. After seeing the review, I wouldn't expect to get cool temps under load with that cooler, unfortunately.
This is wha I think others been recomminding?
http://www.overclockers.co.uk/show [...] subcat=821 with a 120mm fan
- This is the fan as recommended in some topics on these forums;
http://www.overclockers.co.uk/show [...] 7&subcat=4 but with a max rpm of 800 is that going to be enough cooling? I want to OC my 5000 BE to atleast 3.2ghz and with my current cooler it is set to optimal which runs at 2200 and has hadrdly any noise (well I cant hear it)
I think the thermalright ultra120 extreme is just about the best. It is as quiet as the fan you use. Under 1200 rpm, fans are relatively quiet.http://www.anandtech.com/casecoolingpsus/showdoc.aspx?i=2981
60c is a bit hot, but your original post said 40+ under load which is very good. I think the throttling point is at about 65c.
ultra 120 is just the heatsink without a fan, so with that your sayin if i get 1200rpm fan it will be fine? Even tho its will running 40%then my current cpu cooler!

Sorry i didnt explain this properly, i am using a dual core cpu and using temp checking programs lie core temp it shows sep temp's for each cpu, so seperately yes its below 40c but put together its around 60c
What you should see is the temperature of each core. They are not additive. These temperatures may not be perfectly accurate, depending on the monitoring program. I use speedfan which keeps a temperature on my task bar.
For a quiet system, a 120mm fan of 800-1200rpm should be enough, and still be quiet. Yate-loon fans are good, quiet, and cheap; there are others.

so your saying I need to stop adding the 2 seperate temps together? therefore with cpu1 being as 25 and the cpu2 being as 35 it is fine?
Thats good to hear, seems like the cooler is working then?
since I posted this topic Iv had the case side open and it is nowhere near as hot, infact near the PSU/above the CPU it is almost as cool as the HD's, so I will definately be getting side fan put on it, 1 thing I have made a mistake on...
- The Akasa Revo AK-925 (cpu cooler) facing upwards (towards the PSU) actually doesnt blow air upwards its blowing it downwards towards the GPU so thats a good thing.
Iv decided to get the HS and fan plus a side fan, planning on putting side fan in and then seeing how the case is cooled etc, plus putting new MX-2 thermal paste. See how that goes and then if cpu/case still isnt cooled I'l put the new thermalrite HS and the new fan.

Not sure if you know or understand, Core 2 Duo's have 3 sensors. One is referred as the Tcase sensor. This would be the temp that you would see in the bios, speedfan, or MB utility app. The Tcase sensor sits between the cores or gives the temps for the IHS (Intergrated Heat Spreader) or the metal cap on the CPU. The other two are on the die or cores themselves which will give a hotter reading. They are referred to as the Tjunction or DTS (digital thermal sensor). So you'll have separate temps for each core.
Does your PSU have a bottom fan? I only ask since you said "AK-925 (cpu cooler) facing upwards (towards the PSU) actually doesnt blow air upwards its blowing it downwards towards the GPU". I would disagree if you have a PSU that has a fan on its bottom. You will have 2 fans, one will be trying to pull air up the other down, which would cause a vacuum lock, which leads to bad airflow.
I saw the pic of your case, though it didn't show the insides to get a better understanding on whats going on. It seems to look like the traditional airflow type, from your drawing.

You should cut a hole in the side for a fan. I did that with my case, and it made the temps go way down. Not that I have the same case as you, so your results may vary. But, it is fun to mod your case. I have been slowly modding an old Compaq case over the years, it doesn't look anything like it used to.
Its a AMD 64 x2 5000 BE = Dual core 64 bit CPU, so regarding the temp sensors dont think that applies atm I have jsut sent my GFX back and waiting for refund agreement, so I can place order for new card.
@basketcase - thats exactly what im planning, Ive posted link to my case in the first post - Akasa Eclipse 62 (something like that).. Im thinking of making a card board based tube for direct extraction of CPU heat via side case (so that will be 1 hole) and 1x 120mm hole for 120mm side fan...
Thanks for the link, but its old and I read THG every night, so Im kinda upto date with these reviews. Part 2 was saying the best cooler is some £15 cpu cooler which doesnt look brill compared to the cooling of the HS and Fan setup Ive chosen. Both them reviews dont include such coolers as I have chosen and am looking at so its not relevant to me.
Thanks for all the advice/replies in here, Iv placed the order already just the Heatsink is out of stock and the CPU thermal remover is also out of stock so till they arrive Im planning on modding side case for the side fan I got, I will update this thread for any other readers who have similiar questions and may find this information useful.
PS. Will include pics too, this will be my first time modding a case so it may not be the best modded side case.
, I have tried to make the diagram look as accurate as possible and so as you can see the PSU takes air from the case and uses that to cool the PSU then blows it out the back (correct me if im wrong), but as the PSU back end is at the top of the case the hot air from CPU is being blown into the PSU, I dont think the air comming from the front reaches this far to help aid cooling CPU/PSU/RAM - it is most likely being sucked in by the GFX cards fan and then blown back down the case.
