Hey all, Since my last thread on temperatures, my system has changed due to some serious bad luck - So I have started a new thread to clear things up and hopefully get some advice from you all. Do you think these CPU temps are a little high for an i7 -950 @ 3.6GHz (HT Off)? with 1.216v. The following is a temperature test I ran, and the steps are in chronological order/sequance I have now installed 3x Sytche GT 1850s to the triple and re-run my tests - These have been labelled as Test 2 and are written in red below. Overall looks like about a 5c reduction. hmmm Test 1 - 13:09 Idle (from cold boot) - 34/35c Test 2 - 18:05 Idle (from cold boot) - 35/36c ---------------------------------------- 13:19 Idle after 10 mins - 39/40c Test 2 - 18:15 Idle after 10 mins - 37/38c GPU 30c ---------------------------------------- 13:29 Idle after 20mins - 42/43c Test 2 - 18:25 Idle after 20 mins - 38/39c GPU 30c ---------------------------------------- 13:43 idle after 34 mins - 43/44c Test 2 - 18:40 Idle after 35 mins - 39/40c GPU 30c ----------------------------------------- 13:49 Switch on Prime 95 (instantly jumps to) 56/57c Test 2 - 18:46 Switch on Prime 95 (instantly jumps to) - 52/53c GPU 30c ---------------------------------------- 13:54 Prime 95 (after 5mins) 59/60c Test 2 - 18:51 Prime 95 (after 5 mins) - 54/55c GPU 32c ---------------------------------------- 14:04 Prime 95 (after 15mins) 61/62c Test 2 - 19:00 Prime 95 (after 15 mins) - 56/57c GPU 33c ---------------------------------------- ------------------------------------------- 14:13 Switch on furmark (while leaving Prime 95 running): GPU jumps to 59c instantly CPU to 64c 19:07 Switch on furmark (while leaving Prime 95 running): Test 2 - GPU jumps to 52c instantly CPU to 57/58 -------------------------------------------- 14:23 after 10mins of Furmark + Prime 95 CPU = 71/72c GPU = 68c Test 2 - 19:17 after 10mins of Furmark + Prime 95 CPU = 64/65 GPU = 62c -------------------------------------------- 14:30 after 17mins of Furmark + Prime 95 CPU = 75/76c GPU = 71c Test 2 - 19:25 after 18mins of Furmark + Prime 95 CPU = 66/67c GPU = 62c --------------------------------------------- 14:30 Switch off Furmark + Prime 95 CPU Instantly drops to 60/61c Test 2 - 19:27 Switch of Furmark + Prime 95 CPU Instantly drops to 52/53 GPU = 42.8c --------------------------------------------- 14:34 CPU idle 52/53c Test 2 - 19:34 CPU Idle - 42/43c GPU 34.3c --------------------------------------------- This is my setup:- I7 950 @ 3.6GHz (HT off) Voltage @ 1.216v (in cpuz) 3x 2gb XMS3 GA UD5 X58 GTX 480 Corsair AX850 500gb Sammy F3 TJ07 Loop:- Swiftech MCP655-B pump with EK top >> GPU (EK full cover block) >> CPU (EK Supreme HF, CU) >> Double rad (Thin) >> Dual EK Spin Res >> Triple rad (Thin) Fans on the triple are Sycthe Gentle Typhoons 1850s Fans on the double are Enermax twisters Any thoughts on what the problem could be would be very much appreciated. thank you
I think the rads aren't enough personally, technically you have less rad then me even though your using 2 rads. And that pump is easily enough for it, as your putting less restriction in the loop than mine.
hes got a 240 and a 360? Surely that would be more than enough? perhaps the waterblock/TIM isnt fully on?
Thin radiators, depending on fin density and the fans mounted on them; in my experience pull configurations are better suited than push I'd swap out the 360 for a deep rad as I assume the 240 is the roof mount?
They're both the think versions, so they have max of half the capacity of a XSPC RX series rad. And that 480 & i7 kick out masses of heat...
basically what Pete said, and that pump is more than up to the job of what you have, best pump there is in my opinion
Your quite right. The double is in the roof. If i swap the triple in the bottom for a thick rad i might have to re-think the location/fitting of my pump.
TJ07. So are we saying to replace the bottom triple with a thick rad, and then perhaps get rid of the double in the roof? Or keep the roof rad in?
Keep the roof rad and change the fan config to pull for that if possible and either a 360 or better still a 480 thick rad in the base would be my advice yes mate
All fans are pulling on both rads. Hmm okay lads. I have a look see inside the case and see how i can get things to fit. Im tempted to take the roof rad out to improve flow, or do we think all is ok with it in?
You could do that also but then I'd definitely recommend a thick 480 in the base, a Phobya G-Changer V1.2 480mm Quad Radiator will set you back £76.59 from specialtech. http://www.specialtech.co.uk/spshop...ad-Radiator--G-Changer-480-V12-pid-12194.html I recommend both the rad itself (I have 2 x 120's in the base of my Phantom) and specialtech are excellent suppliers
Using a rad that's double the thickness doesn't automatically double the performance, you may lose a few degrees in temps only, check out the performance of a Swiftech MCR at http://skinneelabs.com/triple-radiator-comparison-v2/4/. It would be interesting if you could find out which make and model they are. Older ones won't be as efficient as newer ones though. Rads don't normally have a lot of restriction unless it's one of the older Black Ice ones. I ran 2 quad rads, 2 GPU blocks and a CPU block from a 655 (setting 5) without problem. Check for blockages/gunk in your loop, the GPU fittings as I mentioned in my PM and whether the pump is operating properly. You'd get better cooling with higher performing fans. Edit: While I remember, check out the performance of the BI SR1, that's a 'thin' rad compared to an RX series but has good performance Edit2: Stick a thermometer in the res if you can and we can look at water temps to try and get an idea of what's going on.
Right, im aiming to get a thermometer to test ambient room temps, and water temps today. Gpu fittings and thread info, I will re read my pm from elf and try to provide the info. Pump wise, I dont think you can adjust the power of this one like some of you seem to be suggesting? I think in the bios its reported to be running at circa 4000 rpm but I will check this and confirm tonight
The MCP655-B doesn't have speed adjustment; it's hard set to the equivalent setting of "4" on the MCP655. Still an excellent pump though, should be no issue there.
